FRESH MARKET CUCUMBER VARIETY TRI~tALtFALL 1989
T. K. Howe and W. E. Waters1
Florida vegetable statistics for 1987-1988 indicate that the value of
fresh market cucumbers was $54.78 million (2). The production of 5.7
million 55 lb-bushels came from 14,850 acres. The value of cucumbers was
only exceeded by tomatoes, peppers, strawberries, sweet corn, watermelon
and lettuce. Cucumbers are grown across the state, but concentrated in
the southwest, southeast and west central areas. In 1987-88, 26% of the
production came from west central Florida (2). Commercial production in
west central Florida largely occurs on raised, mulched beds with seepage
irrigation, whereas in other areas these conditions may not apply. A
variety trial at the GCREC was conducted in the fall of 1989 to screen
fresh market (slicing-type) cucumbers for use in west central Florida.
MATERIALS AND METHODS

Raised beds of EauGallie fine sand were formed on August 11, 1989. The
33-inch wide beds were spaced on 5 ft centers with seepage irrigation
ditches spaced every 6 beds. An acre was equivalent to 8712 linear feet
of bed. Fertilizer included 18-0-25-2 (N-P20O-K20-MgO) at 153 lb/1000
linear feet of bed (LFB) (1333 lb/A) placed in 2 grooves 10 inches to each
side of bed center. Beds were fumigated with Vorlex at 4.0 gal/1000 LFB
(35 lb/A) and covered with white polyethylene film. Seed of all entries
(Table 2) were field sown on August 30, 1989. Four replications of 12
plants per cultivar were arranged in a randomized complete block design.
The crop was scouted for pest problems throughout the season. Insect pests
included assorted lepidopterous larvae and sweetpotato whitefly.
Populations were managed with esfenvalerate, methomyl, oxamyl,
insecticidal soap, and Bacillus thuringiensis. Preventative applications
of the fungicides chlorothalonil and mancozeb 80 were utilized throughout
the season to control mildew, anthracnose, target spot and gummy stem
blight. These diseases did not appear during the trial. Prevailing
weather conditions for September and October 1989 appear in Table 1 (6).
Cool temperatures on October 20, 21 and 22 terminated the trial on October
23 after seven harvests.

Cucumber fruit were harvested three times a week beginning on October 9
and concluding on October 23 for a total of 7 harvests (See Table 5 for
harvest dates). Fruit were sorted into U.S. Fancy, No. 1, and No. 2 and
unmarketable categories according to the U.S. Standards for grades of
cucumbers (1). Once sorted, fruit was counted and weighed.
RESULTS AND DISCUSSION

Greatest total yield for all grades was similar for 18 of 25 entries in
the fall trial (Table 2). Total yield ranged from 28 bu/1000 linear feet
of bed (LFB) to 68 bu/1000 LFB. Twenty entries were similar in the total
yield of U.S. Fancy fruit. U.S. Fancy yields ranged from 12 bu/1000 LFB
to 38 bu/1000 LFB. Greatest U.S. No. 1 yield was produced by 14 entries
and all exceeded 15 bu/1000 LFB. U.S. No. 1 yield ranged from 8 to 23
bu/1000 LFB. U.S. No. 2 yield ranged from 5 to 16 bu/1000 LFB, with
eleven entries similar to the 16 bu yield.

Cull production ranged from 4.7% for 'Poinsett 76' to 34.2% for 'A & C
1811'. Seven other entries: 'Encore', 'Early Triumph', 'Slice Top',
'Dasher II', 'Maximore 100', 'Supersett', and 'Revenue' were similar to
'Poinsett 76' in low cull production.

Average fruit weight for the U.S. Fancy grade ranged from 8.6 oz for 'HMX
8424' to 11.4 oz for 'Monarch'. Nine other cultivars were similar in U.S.
Fancy fruit weight to 'Monarch'. Average fruit weight for U.S. No. 1
fruit ranged from 7.2 oz for 'Slice Top' to 9.3 oz for 'Monarch'. Average
fruit weight for U.S. No. 2 fruit ranged from 6.0 oz for 'Early Triumph'
to 8.3 oz for 'HSR 181'.

To indicate earliness, yields from the first harvest appear in Table 3.
Total (all grades) early marketable yields ranged from 2 to 24 bu/1000
LFB. Eleven entries were similar in greatest total yield. U.S. Fancy
yield ranged from 1 to 13 bu/1000 LFB at first harvest, with 15 entries
with similar high yield.

The percentage of total seasonal marketable yield by grade is in Table 4.
All entries produced at least 43% of their respective yields as U.S. Fancy
fruit. Ten entries produced at least 55% as U.S. Fancy fruit and four
entries; 'Dasher II', 'MS 292', 'Flora-Cuke', and 'HMX 8424' produced at
least 60% as U.S. Fancy fruit. U.S. No. 1 fruit ranged from 21 to 36% of
the total marketable harvest, while U.S. No. 2 fruit accounted for between
13 and 28%.
The concentration of fruit production is given in Table 5. While all
entries were picked on the first harvest date, only 5 produced at least
30% of their total yield at the initial pick. Overall, the second, third
and fourth picks produced fewer fruit than the fifth harvest. All but
four entries produced less than 10% of their total yields at the final
harvest.

Most of the entries in this trial were among the best performing in terms
of total yield and early yield. In alphabetical order those were:
'Centurion', 'Comet A II', Dasher II, 'Flora-Cuke', 'HSR 181', 'Maximore
100', 'Monarch', 'Olympian', 'Prolific', 'PS 184', 'Revenue', 'Slice








Nice', 'Spring 440 II' and 'Supersett'. All of these produced good early
and total yields in the U.S. Fancy category. Of these 'PS 184', 'Maximore
100', 'Revenue', 'Sprint 440 II', 'Supersett' and 'Dasher II' were also
highlighted as superior entries in the fall 1988 trial at this location
(5); 'Dasher II', 'Supersett' and 'Revenue' were selected as best in a
north Florida trial (4); and 'Supersett', 'Centurion' and 'Dasher II' were
in common as good cultivars in a fall 1989 Leesburg trial (3).

Total seasonal yields from this trial were from 0.6 to 1.5 times the state
commercial average (2).
