SNAP BEAN VARIETY AND STRAIN TEST
19 8
James C. Hoffman

The test consists of 31 seed stocks planted November 11, 1947. The plots were
established as a balanced incomplete block. This type of field design varies from
the lattice square design only in that 6 additional seed stocks were added. Each
variety or strain occurred with every other variety or strain once, but never oc-
curred with any variety or strain more than once. There were a total of 31 blocks
and 6 replications of each line. Each replicate consists of a single row h0 feet
in length. Spergon treated seed were planted 2 inches in depth with an Equa-Space
Seeding Mechanism at the rate of 6 seed per linear foot. The rows were spaced 28
inches apart.
Fertilizer was applied November 5 at the rate of 400 pounds of 0-8-24, 25
pounds manganese sulphate, 25 pounds copper sulphate, 25 pounds zinc sulphate and
10 pounds borax per acre, in 2 bands 3 inches on each side of the seedbed and 3
inches in depth.
The plots were located on well mature sowgrass peat with a pH of 5.75.
Since powdery mildew and several strains of rust are prevalent in the Belle
Glade area, the crop was sprayed with a mixture of 20 pounds of wettable sulfur in
100 gallons of water at the rate of 125 gallons per acre. To this sulfur spray,
which was applied on the 12th, 19th, 26th and 33rd day after seeding, was added 2
pounds of manganese sulphate and 1 pound of zinc sulphate per 100 gallons of spray
solution. There were no visible nutrient deficiency symptoms during the growing
season with the exception of a slight manganese deficiency which developed on the
50th day or when the majority of fruit had developed to marketable maturity.

The crop grew extremely well as the existing climatic conditions were very
favorable. The temperature for the growing season averaged 70.50 F. for the period
from 6:00 A.M. to 6:00 P.M., and 62.60 F. for the period from 6:00 P.M. to 6:00 P.M.
or a general average temperature of 66.60 F. for the bean growing season. At no
time was moisture a limiting factor as the water table was held at 24 inches during
the season.
The data as presented show the importance of breeding and selection for de-
sirable bean qualities and high yielding stocks. It is of interest to note that 4
of the 6 stocks that significantly out-yielded the Tendergreen average are new bean
progeny that.have never been introduced or given a variety name. These beans also
have excellent edible quality.
A description of each numbered column is outlined to clarify the data as
presented:
TABLE 1. (1) Thickness was measured in millimeters with a vernier caliper, the
average as listed represents 100 measurements on separate fruit. These
measurements were not taken at constricted locations.
(2) Same method as 1.
(3) Thickness divided by width gives a shape index as follows:
0.60 and below is flat fruit; 0.60 to 0.80 is oval; and 0.80 to 1.20 is round.
(4) Straightness: 1 Pencil straight 3 Badly curved
2 Slight curve 4 Curved in two directions.
(5) Length: Average of 100 fruit to the nearest inch; any difference
of 0.01 of an inch is considered highly significant as calculated by variance
analysis.
(6) Color: 1 very dark 3 medium
2 dark h light.
(7) Roughness: 1 very smooth 3 slightly rough
2 smooth 4 very rough (roughness is usually
caused by constrictions between the seed).
(8) Uniformity: A relative scale, 1 being extremely uniform and 5 being
extremely irregular.
(9) Fruit were number 5 grade.
(10) Plant Height: Measured from soil to tip of longest leaflet.
(11) Height of Pods from Soilt 1 well above soil 3 touches soil
2 clear of soil occasionally
4 touches soil
badly.
(12) Plants Par Foot: Iverage random sample of 10 feet, taken at
6 locations or replicates.
TABLE 2. (1) Based on total harvest of 2 pickings.
(2) Mean yield is the mean of 6 replications 40 feet in length, weighed
in pounds.
(3) Mean yield in column 2 multiplied by the factor 15.75.
(4) Estimated variety means adjusted by calculation of variety and block
totals. The significance of these data are explained by a study of Table 3 and notes.
