grade are the peas. The best returns can be realized when the crop
is harvested by grades rather than by yields. Quality rather than
quantity is the determining factor in accepting vegetable produce,
and the peas that are young and tender command a higher price in
The California station has found that storage temperature has
direct bearing on the storage life of summer squash. Squash remains
in marketable condition for about 14 to 17 days when stored at 32
F., for 14 days at 50, for 8 days at 60, and for only 6 days at 70.
Observations were made of the appearance of fruits during the storage
periods, and the changes in chemical composition were studied.
Fruits of Early Prolific Straightneck summer squash were used to
determine the quality changes in squash shipped to distant markets
at various temperatures.
Testing New Varieties
In carrying on vegetable variety research it is necessary not only
to develop new varieties, but also to test these varieties under various
environmental conditions before they can be recommended to the
seed trade and the public. A number of State experiment stations
devote special attention to the testing of new varieties from nearby
and distant States. These trials generally are cooperative
among different stations and between them and the Department of
An outstanding example of cooperative vegetable research is that
done through the United States Vegetable Breeding Laboratory at
Charleston, S. C. The program is a cooperative one between the
Department and State experiment stations, particularly in the South.
One specific phase of this work is that concerned with the improvement
of tomatoes. Known as the Southern Tomato Exchange Program
(STEP), specialists from the laboratory and from southern and
other experiment stations attack breeding problems as a team. Promising
varieties are exchanged for trials at the different locations prior
to release to growers, the seed trade, and commercial and home
The Northeastern Cooperative Trials, another agency for testing
varieties, uses the facilities and services of research workers at the
State experiment stations in the northeastern region.
Among outstanding State experiment station trials are the ones
conducted by the Pennsylvania station which, in 1951, grew and evaluated
15 eggplant, 9 rutabaga, 33 garden pea, 73 tomato, 53 snap bean,
27 cucumber, 110 sweet corn, 23 beet, and 21 carrot varieties and
strains. Detailed records of the trials are published and have been
made available to the public. On the basis of observations in trials
made at different locations in the State, the New York (Cornell) station
since 1934 has issued 15 reports on the newer varieties of vegetables
for the guidance of home and commercial gardeners.
From the Texas station a new variety of green-sprouting broccoli
has been announced under the name Texas 107. This variety is noteworthy
because of its high production of marketable side shoots.
