HORTICULTURAL TRIALS WITH BUSH SNAP BEAN VARIETIES, STRAINS
AND BREEDING LINES. 1954-55 SEASON
Emil A Wolf*
On the basis of total acreage grown, green beans continue to be one of the
most important vegetable crops in the Everglades area. In the search to find better
varieties for the area, two varietal trials were carried out during the 1954-55 sea-
son to obtain information on adaptability and potential usefulness of several new
varieties and strains being offered growers as well as a large number of unreleased
breeding lines and strains under development by commercial, U.S.D.A., and experi-
ment station breeders,
The fall trial, planted on October 21, was severely damaged by heavy frost on
the morning of December 20 just as the earliest varieties were ready to be picked.
No yield records were possible but observations made on this planting are worthy
of discussion. The 14 Southern Cooperative Snap Bean Trial Observational Entries
(listed in Table 2 of Everglades Station MIimeo Report 55-3) and three other repli-
cated entries--Seminole, B 2194-1-1, and B 3077--grown in the 1954 spring trials
were included in this test to check their performance under the less favorable grow-
ing conditions of late fall and early winter. Upon harvesting a hollow condition
was noted in the flesh of the pods between the seed cavities of most of the round
podded varieties and lines. Rogers Improved Tendergreen and Regional Vegetable
Breeding Laboratory B2567-1, a prolific dark podded, Tendergreen type, considered
to be the two best varieties in the trial, were about the only round podded varie-
ties in addition to Tendergreen not showing some degree of the hollow condition in
their pods. Hyscore, Hashburn Wilson's Improved Tendergreen, B2194, B2456, B2720,
B2920, Ferry Morse H1050, and Seminole were all badly affected. This hollow condi-
tion in the pods occurred in a number of fields in the area and a considerable
number of complaints were voiced by buyers for freezers during the fall on the ex-
tent of the hollowness in beans grown in the area during this season. The develop-
ment of the hollow spaces between the seed cavities may have been the result of
rapid growth due to extremely favorable growing conditions or some other underter-
mined reason or reasons. However, there can be no question that some varieties and
strains such as Seminole and the others indicated above are more susceptible to
development of the hollow condition. In this trial also, pods of the Rogers Improv-
ed Tendergreen developed a considerable amount of purple coloration due to the cold
weather which was not the case with the regular Tendergreen.
In the spring, eight varieties and breeding lines listed in Table 1 were com-
pared with standard Tendergreen and Black Valentine varieties in a regular replicate(
yield trial. There were five replications of single rows 20 feet long in this test.
Twenty-seven additional varieties listed in Table 2 were grown for observation in
single 30 foot rows from which indications of potential yielding ability was obtain-
ed by harvesting a 20-foot section of each row. Rows were three feet apart with
plants spaced 1 to 2 inches apart in the rows. All varieties and lines were picked

three times as they reached the proper stage of market maturity except for three en-
tries in the observational trial which did not produce a third set.
Good growing conditions prevailed and very good yields were obtained. No
rust or other diseases were present. Contender, as usual, yielded very heavily.
Of the eight round podded vaieties and strains, B2567-1, New Improved Tendergreen,
Seminole, Tenderlong 15, and Northrup King's Tendergreen, all significantly out-
yielded the standard Tendergreen variety supplied by E. T. Bailey and were consid-
ered superior to it in one of more characteristics, B2567-1, is a new mosaic re-
sistant line developed by the Regional Vegetable Breeding Laboratory at Charleston
which produces attractive dark pods that wilt more slowly than those of Tendergreen,
This line was rated as one of: the best new lines in the 19l5 spring trials and per-
formed well again in the fall. The pods may be a little fibrous and a freezer re-
ports excessive sloughing of the outer skin in a test lot. Seminole again produced
a very good yield of smooth, attractive pods. Some hollow spaces were noted in the
flesh of the pods between the ,seed cavities of this variety though not as extensive
as in the fall plantings. The New Improved Tendergreen produced very solid pods
but these were very rough and were not as attractive as Seminole pods. They were
superior to the regular Tendergreen, however, in length and appearance. Tenderlong
15 produced very well in this trial and was considered superior to the regular Ten-
dergreen as was the case with the Northrup King strain of Tendergreen.
Of the 27 varieties and strains in the observational tests, Corneli's Improv-
ed Tendergreen and Regional Vegetable Breeding Laboratory B2530-6-2-4 were consider-
ed to be the most promising. This is the second year that the latter line has been
chosen as one of the best in the observational tests. It produced a very heavy firs
picking of medium green, straight, sound, meaty, smooth pods. MIany of the varieties
received low ratings because their pods touched the soil badly. This is the result
of short bushes setting pods too close to the ground, or failure of the plant to
hold up a heavy yield. Plants of Hyscore, White Seeded Tendergreen, and B2920-2
broke off badly at the ground level when picked. Pods of 101-B showed more greenish
cast and green tips than Cherokee Wax. Stem ends of Processor pods were very long,
indicating high snipper loss. Improper pollination was also noted in some of the
pods. Irregular set resulting in delayed harvest and variable maturity was noted
on Stringless Black Valentine, Improved Wade, H4066 and H4068.
