General Comments:

Chip potato production is valued at over $100 M annually in Florida. Chip potatoes are grown in many areas of the
state although the greatest concentration of chip potato acreage (20 k + acres) is in Hastings. The goal of the Snack
Food Association Potato Variety Trial is to find a chip potato with better quality and production characteristics than
Atlantic, the standard Florida chip variety. Varieties and clones are submitted for evaluation in the program by
unviersity, USDA, and private breeding programs. Clones are evaluated under Florida's short day growing conditions
for higher gravity, better production, improved chip color, and improved disease resistance compared to Atlantic. (See
Tables 1, 2, 3 and 4.)

Planting Site: Hastings REC, Yelvington Farm
Planting Date/Harvest Date: February 16, 2001; June 4, 2001
Season Length: 108 days
Growing Conditions: A dry season with average temperatures and a low incidence of Late Blight resulted in higher
than average tuber yields in North Florida.
Experimental Design: Each variety/clone was planted in a single 200 ft row as dictated by the SFA protocol. Four
20 ft sections of each row were harvested and graded. This was not a replicated experiment. Only means were
calculated.

I QCopper Toxicity of Vegetable Crops

Copper (Cu) is an essential micronutrient for plant growth. It is an important component of proteins found in the
enzymes that regulate biochemical reactions in plants. Copper-deficient plants are stunted and have short internodes
and necrotic young leaves. Optimal Cu contents in leaves for most vegetable crops are 1-10 ppm. Copper deficiency
often occurs in soils with high pH and in organic soils where Cu is completed to organic substances. In early 50s, Cu
fertilizer significantly increased crop production in Belle Glade area. Most mineral soils in Florida contain adequate
amounts of Cu for optimum vegetable yields. Actually, high Cu concentrations in some soils cause toxicity to crops.

A recent study reported the background Cu concentrations for Florida surface soils are 0.2-22 ppm. However, some
soils have as high as 1500 ppm for total Cu and 200 ppm for plant available Cu. Copper was accumulated in soils
through application of fungicides, fertilizers, animal manures, and municipal solid wastes. Copper-formulated
fungicides are probably a main source for most high Cu soils.

Copper toxicity to citrus was first reported in Florida as early as 1954. We did not find literatures on Cu toxicity to
vegetable crops in Florida. However, for last several years I have seen Cu toxicity symptoms on various vegetable
crops in south Florida. Recently, we evaluated effects of Cu on 6 vegetable crops (mustard, Chinese cabbage, tomato
pea, sweet corn, snap bean) in the Indian River Research and Education Center at Ft. Pierce. Growth of mustard,
tomato and sweet corn were significantly reduced in the solution containing 10 ppm Cu. Chinese cabbage, pea and
snap bean relatively resisted to Cu toxicity.

Copper toxicity symptoms include plant stunting, a bluish tint to leaf color, and leaf cupping followed by chlorosis or
necrosis. Feeder roots may become darkened. Crops planted in high Cu soils often show iron deficiency symptoms.
Some literature suggested that the Cu toxicity concentration in leaves is 150 ppm while other proposed toxicity levels
as low as 20-30 ppm. There are large differences in Cu tolerance among crops. Bean is much more tolerant than
sweet corn.

Copper is tightly adsorbed by most soils and will not easily leach. Therefore, once Cu accumulates in a soil and
toxicity problem develops, it is very difficult to alleviate it. Several approaches may prevent or reduce Cu toxicity to
vegetable crops: 1) testing soils before planting vegetables, especially for old citrus or avocado lands; 2) planting
Cu-tolerant crops or varieties; 2) liming acid soil to pH 6.5; 3) using soil organic amendments; and 4) apply iron and
other fertilizers to stimulate root growth.

Spring 2001 GCREC Canta.loupe Variety Evaluation


Cantaloupe is included in the melon group Cucumis melo cantalupensis in the Cucurbitaceae family. Cantaloupes are
a relatively minor crop in Florida so there are no data available on commercial acreage, yield, production or value.
However, there has been a great increase in production in west-central Florida and throughout the state in recent
years indicating the potential for a strong commercial cantaloupe industry in Florida.

The ideal shipping variety for Florida should combine the following traits: (1) capacity to produce high yields; (2) fruit
that is sutureless or nearly so, round to slightly oval, fully netted, a minimum 3 Ib weight with a thick, deep salmon
interior, a small, tight seed cavity, and high soluble solids; (3) a pleasant aroma and taste; and (4) resistance to fruit
rots and foliar diseases, especially downy and powdery mildew. 'Athena', introduced several years ago, has become


Page 8








http://peaches/hochmuth/vegetarian.htm


the industry standard and is largely responsible for the increased acreage. The object of this trial was to further
evaluate outstanding varieties from the 2000 trial to identify slightly sutured, heavily netted cantaloupe varieties for
potential production in west-central Florida.

Ten cantaloupe hybrids were direct seeded on 15 March in holes that were punched 2 ft apart in the black
polyethylene mulch. The 20-ft long plots contained 10 plants each and were replicated four times in a randomized,
complete block design. Weed control in row middles was by cultivation and application of paraquat. Pesticides were
applied as needed for control of silverleaf whitefly endosulfann), downy mildew (chlorothalonil, fosetyl-aluminum,
azoxystrobin, thiophanate-methyl, and maneb), powdery mildew (trifoxystrobin), and lepidopterous larvae (Bacillus
thuringiensis, spinosad, esfenvalerate, and methomyl).

Cantaloupes were harvested eight times beginning on 28 May and ending on 13 June. Marketable fruit were separated
from culls that included fruit weighing less than 2.0 Ib or that were cracked, rotted, or poorly shaped. Observations
were made on fruit shape, sutures, and netting. Soluble solids were determined with a hand-held digital refractometer
on several fruit from each entry on several harvest dates.

Early yields, as represented by the first two of eight harvests, ranged from 21 cwt/acre for 'Odyssey' to 483 cwt/acre
for RML 8726-VP (able 1). Average fruit weight of early-harvested cantaloupes varied from 4.8 Ib for 'Athena' to 8.8 Ib
for 'Minerva'.

Total marketable yields for the entire season varied from 514 cwt/acre for RML 9602-VP to 773 cwt/acre for RML
8793-VP (able 1). Seven other entries had yields similar to those of RML 8793-VP. Average fruit weight ranged from
5.0 Ib for 'Athena' and PXC 221 to 8.6 Ib for RML 9601-VP which was statistically superior to all but one other entry.
Soluble solids varied from 10.7% for RML 9602-VP to 13.2% for RML 8793-VP. Very good internal quality is used to
describe cantaloupes containing not less than 11% soluble solids. Using this criterion, all but three entries qualify for
the very good internal quality designation. Cull fruit was between 64 cwt/acre for RML 8793-VP and 298 cwt/acre for
RML 8797-VP. The principal causes of cull fruit were stem-end cracks, fruit rots and misshapen fruit. Marketable fruit
per plant varied from 1.7 for RML 8797-VP to 3.3 for 'Athena'.

Previous cantaloupe variety evaluation trials were conducted at this location in the spring 1988, 1990, 1991, 1999 and
2000 seasons. Total marketable yields from cantaloupe hybrids in 2001 ranged from 514 cwt/acre to 773 cwt/acre, in
2000 yields varied from 265 cwt/acre to 681 cwt/acre; in 1999 they ranged from 382 cwt/acre to 660 cwt/acre; in 1991
yields varied from 327 cwt/acre to 547 cwt/acre and in 1990 yields ranged from 300 to 566 cwt/acre. Accordingly,
yields in recent years are about 100 cwt/acre greater than those obtained a decade ago. In 2001, yields were still
higher with the yields being related largely to large fruit size. Also, some of the more recently introduced hybrids are
more dependable producers and have better shipping qualities than those previously available. 'Athena' remains the
leading variety. However, growers may want to make trial plantings of 'PXC 221', 'Odyssey', 'Eclipse', or 'Vienna' to
evaluate their performance on their own farms.

ISpring 2001 GCREC Tm.ato Variety Evaluation

In 1999-2000, 43,200 acres of tomatoes were harvested in Florida, yielding 62.2 million 25-pound cartons worth over
$418 million. Tomatoes accounted for almost 30% of the total value for all vegetables grown during 1999-2000, making
it the most important vegetable produced in the state. The Palmetto-Ruskin area (west-central Florida) accounted for
over 36% of the state's total fresh market tomato production in 1999-2000.

A tomato variety trial was conducted in spring 2001 at the Gulf Coast Research and Education Center Bradenton
located in west-central Florida to evaluate fresh market tomato varieties and breeding lines. Twenty-nine entries were
evaluated in a replicated yield trial.

Seeds were sown on 9 January into planter flats (1.5 x 1.5 x 2.5-inch cells) containing a commercial mix (60%
sphagnum peat moss and 40% vermiculite with 3 pounds dolomite, 1 pound Micromax [microelements] and 1 pound
gypsum per yd3). Transplants were fertilized periodically with a liquid 20-20-20 (N-P205-K20) to sustain growth during
production. Plants were conditioned before transplanting by limiting water and nutrients in the final phase of

production.

The Eau Gallie fine sand in the experimental area was sampled before fertilization and analyzed by the University of
Florida Extension Soil Testing Laboratory (Hanlon and DeVore, 1989): pH = 7.3 (target pH is 6.5) and Mehlich I
extractable P = 147 (very high), K = 48 (medium), Mg = 114 (high), Ca = 1058 (adequate), Zn = 10.2 (adequate), Cu =
6.3 (adequate), and Mn = 8.8 (response possible) ppm. The land was prepared in early February. Beds were formed
and fumigated with methylbromide:chloropicrin, 67:33 at 2.3 lb/100 Ibf. Banded fertilizer was applied in shallow groove
on the bed shoulders at 2.52-0-3.50 Ib N-P205-K20/100 Ibf after the beds were pressed and before the black
polyethylene mulch was applied. The total fertilizer applied was equivalent to 220-0-305 Ib N-P205-K20/A. The final
beds were 32-in. wide and 8-in. high, and were spaced on 5-ft centers with six beds between seepage
irrigation/drainage ditches, which were on 41-ft centers.

Transplants were set in the field on 25 February and spaced 24 in. apart in single rows down the center of each bed.
Transplants were immediately drenched with water containing 16 fl. oz/acre of imidacloprid for silverleaf whitefly
control. Four replications of 10 plants per entry were arranged in a randomized complete block design in the replicatec
trial and single 10-plant plots were used in the observational trial. Plants were lightly pruned, staked, and tied.

Plants were scouted for pests throughout the season. Lepidopterous larvae, silverleaf whitefly, and russet mites were
the primary insects found. Bacillus thuringiensis, abamectin, indoxacarb, spinosad, endosulfan and tebufenozide were
used according to label instructions to manage insect pest populations during the season. A preventative spray
program using maneb, copper hydroxide, azoxystrobin and chlorothalonil was followed for management of plant
pathogens. Tomato yellow leaf curl virus plants were removed and disposed of early in the season, but were allowed tc
remain after the second tie.

Fruit were harvested at or beyond the mature-green stage on 17 and 31 May. Tomatoes were graded as cull or
marketable by U.S. standards for grades and marketable fruit were sized by machine (see footnotes Tables 2, 3 for
specifications). Marketable fruit were counted and weighed, cull fruit was weighed.

Early marketable yields ranged from 209 25-lb cartons for 'Sanibel' to 905 cartons/acre for BHN 543 (able 1.
Eighteen other entries had yields similar to BHN 543. Extra large fruit yield varied from 151 cartons/acre for 'Sanibel'
to 765 cartons/acre for BHN 543. Fifteen other entries had early extra large fruit yields similar to those of BHN 543.
Large fruit yields varied from 30 cartons/acre for BHN 442 to 182 cartons/acre for ASX 013. Average fruit weight for the
early harvest ranged from 5.7 oz for 'Solar Set' to 8.0 oz for HA 3028. Plant stand was statistically similar for all the
entries. Cull fruit by weight for the early harvests varied from 6% for PS 150535 to 61% for 'Sanibel'. There was a high
incidence of blossom-end rot throughout the trial. Other principal defects were large blossom scars, persistent green
shoulders and rough shoulders.

Seasonal marketable yields from two harvests ranged from 1737 cartons/acre for SVR 1440598 to 2821 cartons/acre
for ASX 013 able 2. Twenty-one entries had yields similar to those of ASX 013. All entries produced yields greater
than the state average yield for spring 1999-2000 of 1693 cartons/acre (Vitzig and Pugh, 2000).

Yields of extra large fruit varied from 1244 cartons/acre for 'Sanibel' to 2392 cartons/acre for BHN 543. Twenty-two
other entries had extra large fruit yields similar to those of BHN 543. Large fruit yields ranged from 147 cartons/acre fo
SVR 1405037 to 771 cartons/acre for ASX 013. Cull fruit for the entire season varied from 12% for Fla. 7973, PS
150535, and 'Florida 47' to 32% for HA 3028. Blossom-end rot and persistent green shoulder affected fruit were the
principal defects. Average fruit weight was from 5.8 oz for 'Solar Set' to 7.8 oz for 'Florida 47'. The incidence of tomato
yellow leaf curl virus infection was low and varied form none for PS 150535, BHN 442, Fla. 7816, HA 3057, HA 3028,
and 'Sanibel' to 10% for BHN 575, but there was no significant difference among the entries.

Overall, total marketable yields surpassed those obtained at this location in recent spring seasons. In spring 2001,
yields ranged from 1737 cartons/acre to more than 2800 cartons/acre.

The proportion of extra-large fruit was very high, e.g. about 86% of the BHN 543 and 'Florida 91' fruit were in this size
category. Exceptional experimental hybrid performers in spring 2001 were ASX 013, Fla. 7973, ASX 911, PS 150535,
HA 3026, Fla.7943, Fla. 7816, Fla. 7964, and ASX 174.

! _Sensory. Evaluation of Cantaloupe Varieties in North Florida

Melon is a generic term that refers to the fruits of Cucumis melo L. plants, including muskmelons (often incorrectly
referred to as cantaloupe) and Galia melons (Simonne et al, 1998). Muskmelons have orange flesh and are
categorized as eastern or western type, based on the fruit netting and sutures. The netting is the network of cork-like
marks that cover the rind. Sutures are the meridian lines that divide the rind into several sections. Fruits of
eastern-type varieties are round, have a large seed cavity, and weigh five to seven pounds each. Their rind show
distinctive sutures, with variable levels of netting. In contrast, western-type varieties have oval-shaped fruits weighing
three to four pounds each. Their sutureless rind is covered with a coarse netting. Galia melons, at maturity, have
yellow rind covered with a light net, green flesh with banana-like aroma.

Currently, eastern-type muskmelons are mainly produced in Georgia, South Carolina and the mid-west, while
western-type muskmelons are grown in California, Arizona, and Texas (NASS, 2001). The U.S. field production of
Galia melons is extremely small. Despite favorable growing conditions, current cantaloupe acreage in North Florida
does not exceed 1,500 acres, and state-wide acreage is estimated at 3,000 acres. While recommendations for
cultural practices and variety selection of melons are available, limited information is available on how differently these
types taste, and how consumer would rate them one compared to the other. Therefore, the objectives of this study
was to determine and compare consumer preference of eastern-type and western-type cantaloupes, and Galia melons
grown in North Florida.

In the Spring of 2001, six melons varieties were grown at the North Florida Research and Education Center -
Suwannee Valley following recommended practices (able 1). Melons were harvested at the full-slip stage the day
before the taste test, cut into bite-size pieces, and refrigerated overnight. Soluble solids level was measured using a
hand-held refractometer on six melon pieces selected randomly from each variety.

The sensory evaluation was conducted following recommendations of the American Society for Testing Materials
[ASTM] (1981) on June 4. Twilight field day participants (commercial vegetable growers, gardeners, and Extension
personnel) voluntarily participated in the test. In a quiet seated area, panelists were provided with a plate containing


Page 15








http://peaches/hochmuth/vegetarian.htm


six melon samples coded with random three-digit numbers, a glass of water, a data collection form, and a pen.
Panelists were first asked to provide age group and gender. The first question instructed panelists to provide the
names of melon varieties they are familiar with. They were then asked to taste and evaluate the samples for
crunchiness, sweetness, flavor, and overall preference. Panelists recorded their scores on a 90 mm long, unstructured
line for each attribute. Descriptors were written on both ends to give directions of the scale ig. 1). On the left side of
the lines, terms were associated with unsatisfactory scores such as 'extremely dislike' or 'bland', whereas on the rigl
side of the lines, terms given were associated with favorable scores (full scale) such as 'extremely like' or 'musky'.
Numeric scores were taken by measuring with a ruler the distance between the left side of the line and the panelist
mark on the line.

Demographic and sensory data were analyzed using analyses of variance and Duncan' multiple range test (SAS
2000). Sensory scores were also compared for melon types using orthogonal contrasts 'eastern-type vs. western-
type' and muskmelonss vs. Galia melons'.

Means scores for each attribute and each sample were calculated by adding all the panelists' response and divided b,
the total number of panelists. Then melons varieties were ranked from the first to the last one for each sensory
attribute, where the higher mean score represented the better rating and the lower mean score represented the less
favorable rating. In case of two-way tie at rank n, both samples were ranked as n+(1/2). Next rank was n+2 (Simonne
et al., 1999). The variety having the lowest score received the highest rank. The overall rating was evaluated by adding
for each variety, the ranks of all four attributes. The sum of ranks was called the Overall Rank Sum Index (ORSI).

Panel makeup. A total of 50 data collection forms was correctly filled and was used in the statistical analysis. The
panel was comprised of 22 males, 13 females, and 15 forms did not report gender. Age distribution was 1 panelist in
the 0-9 years-old group, 0 in the 10-19 group, 6 in the 20-29 group, 10 in the 30-39 group, 9 in the 40-49 group, 8 in
the 50-59 group, and 6 in the 60-69 group. Age group was not reported on 10 forms.

Effect of demographic data on sensory scores. Panelist age did not significantly affect crunchiness (p-value = 0.33
), flavor (p-value = 0.07), sweetness (p-value = 0.18), and overall preference (p-value = 0.24). Gender effect was not
significant for flavor (p-value = 0.07), sweetness (p-value = 0.10), and overall preference (p-value = 0.15), but was
significant for crunchiness (p-value = 0.01). Crunchiness ratings (mm) were 44a, 38b, and 30c for unreported gender,
male, and female, respectively.

Effect of variety and type on sensory scores. Because of the orientation of the unstructured lines, low ratings
represent undesirable or low ratings, while high ratings represent desirable, attractive ratings. The lowest and highest
possible ratings were 0 and 90 mm, respectively. The median value for all ratings was 45 mm.

Variety significantly affected crunchiness, flavor, sweetness, and overall preference (all p-values = 0.01). 'Hi-Mark' and
'Mission' had significantly higher crunchiness scores than all the other entries except 'Odyssey". Crunchiness scores
for 'Athena' (29 mm), 'Inbar' (38 mm), and 'Passport' (18 mm) were well below the 45 mm median value. 'Athena',
'Inbar' and 'Odyssey' tended to have higher flavor ratings than 'Mission' and 'Passport'. The lowest flavor rating
('Passport', 42 mm) was close to the median 45 mm value, suggesting that panelists perceived favorably the flavor of
all varieties. 'Inbar', 'Odyssey', and 'Athena' had significantly higher sweetness ratings than the other entries. The
lowest sweetness rating ('Passport', 44 mm) was close to the median 45 mm value, suggesting that panelists
perceived favorably the sweetness of all varieties. 'Athena' and 'Odyssey' tended to have the highest overall preference
rating (63 mm and 58 mm, respectively), while 'Hi-Mark' and 'Passport' had significantly lower ones (43 mm, and 36
mm, respectively). This analysis made separately for each variety shows that no one single variety was perceived as
the best for all the attributes.

The ORSI ranged between 9 for 'Odyssey' to 24 for 'Passport'. Because of the orientation of the rankings, low ORSI
values were desirable, while high ones were not. ORSI values for 'Odyssey', 'Athena', and 'Inbar' were numerically
close (9, 10 and 11, respectively). These three varieties were the overall best rated ones.

Effect of types on sensory scores. All the p-values associated with both contrasts ('eastern-type vs western type'
and 'muskmelon vs Galia melon') were significant, except that of the contrast 'muskmelon vs Galia melon' for
sweetness. Mean flavor, sweetness and overall preference were higher for the eastern type, while mean crunchiness
was higher for the western type. The Galia type rated lowest for all attributes, because of the low ratings received by
'Passport'. These results are rather surprising as Galia melons are known for their attractive, typical flavor.

In conclusion, this panel of 50 members found significant differences among the four major sensory components of
small melons crunchinesss, sweetness, flavor, and overall preference). Different varieties were best rated for different
attributes. When all sensory scores were pooled together using ranking procedures, 'Athena' and 'Odyssey' were the
most preferred varieties, while 'Passport' was the least preferred. When varieties of the same types were analyzed
together, panelists preferred eastern melons over western and Galia melons. These results suggest that growers
should consider planting a small acreage of specialty melons such as the Galia-type along with the more traditional
eastern-type.
