Recommendations:

This field is a pertnanent fumigation study for the commercial
production of chrysanthemums. This tofatd crop *as included
in the mums' "off season" to study the possible accumulation
of fumigant breakdown products toxic to tomatoes.

Purpose: To compare new commercial varieties and experimental sweet corn hybrids
for yield, quality, plant vigor, earliness, uniformity and marketability.

Planting data:
Land had fall crop of tomatoes. Because of heavy residual of salts carry-
over, no fertilizer was applied or soil treatment added in the bed when
made up.

Seed were planted March 10. Plants were thinned to a single plant per
hill on March 17. Row spacing is 54 inches and hill spacing 9 inches.

Fertilizer 4-8-8 total 2600C/A.,ammonium nitrate, 160#/A., sulphate of

TOMATOES: EVALUATION TRIALS

Purposely Evaluation of Gulf Coast Station advanced breeding lines which are con-
sidered potential new varieties compared with Manalucie, Indian River
and the recently released variety Manapal. Evaluations are made on the
basis of quality, yield, size of fruits, earliness and other horticul-
tural characters.

Planting data: Seeds were sown in flats containing sterilized soil on December 27.
Seedlings were transplanted to other flats on January 11 and plants were
set in the field on February 8. Row spacing is 54 inches, plant spacing
16 inches.

Land was treated in the row with VPM and 4-8-8 fertilizer 600 lbs.A.
was applied in the bed when made up. Total fertilizer applied to date
3000 Ibs./A. 4-8-8, 25% organic plus ammonium nitrate 140 Ibs./A., sul-
fate potash + ammonium nitrate 140 Ibs./A.

Plants pruned to 2 stems. To provide sufficient leaf cover at top of
the plants, all pruning was discontinued when plants were about half
grown.

Varieties:
1. Manalucie standard for vine ripe harvest.

TOMATO BREEDING LINES

Varieties and Their Salient Features

Manalucie Standard for vine-ripened harvest and rates best in size and pala-
tability of fruits. Is late and subject to catface.

Indian River Has early-setting habit and is adaptable to ground culture as
well as supported culture, but at 850 F. or warmer weather fruits
ripen too fast for pink-harvest handling. Often sets more fruits
than it can size and is subject to catface.

Manapal Has record of all-around dependability and has already been well re-
ceived by vine-ripened and greenhouse trades. Fruits only slight-
ly smaller than those of Manalucie but considerably superior in
smoothness.

Floralou Very recently released. Has been tested for many seasons under
designation STEP 346. Has earliness, smoothness, excellent qual-
ity, excellent crack-resistance, and uniformity of fruits, but,
in southern Plorida it has too often failed to make market-size
of its nice fruits. In northern Florida and areas to north it
has sized well.

Stocks Still in Developmental and Testing Stages

The 601 CAStW family Shows high yielding potential with earliness, size, and
good quality of fruits. Most interesting prospect for maintenance
of average size of fruits through winter and early spring, when
started as a fall crop, because of fasciation of many of its fruits
formed at 55 F. or lower temperatures. Now in F3 generation.

The 18-D2-04-1 to 11 CAVStW lines These selections, now in the F5 generation,
are resistant to Verticillium wilt. They look promising at Home-
stead and Ft. Pierce as well as on this field, but selecting is
required.

STEP 390 and STEP 408 Considered our best advanced lines resistant to to-
bacco mosaic,

STEP 314 Pink This line originated from a single plant found a year ago in
a population being grown by Dr. J. P. Jones. To date, it appears
to differ from Manapal only in the lack of color in the skin of
the fruit.

Determinates with Concentrated Yield

STEP 386. STEP 409, and STEP 410 are sister selections of the "366" family
that have aroused considerable interest among growers during the
past year. Which is your preference?

STEP 388-1-Bk, which rated best among our determinates in the 1961 STEP trials.

STEP 412, which must be considered our best all-around advanced determinate be-
cause of setting-habit, leaf-cover, quality, smoothness, and crack-
resistance, provided it will size its fruits to suit the market.

Field 11 (continued)

Younger Stocks, Representing Improvements as follows:
709 and 736 CAStW, showing earlier and more concentrated yielding potentials.
654 CAStW selections in F3, showing potentials of improved quality and smooth-
ness of fruits.

Younger Stocks Resistant to Tobacco Mosaic

408-4-1 and 449-1-1 CAStMW, lines now in the F4 generation, offer some en-
couragement that a variety with resistance to TMV and horticultural
characters suitable for vine-ripened usage can be available in the
next few years.

Test of Zemdok

This chemical, developed by the Rohm & Haas Co, and, until recently, tested
under label FW-450, is a male gametocide. Dosage and timing of application
are being studied here because of preliminary evidence acquired several years
ago that this chemical may be very useful on tomatoes for the following two
purposes:

1. To make unnecessary the hand emasculation of flowers and thus greatly
reduce the cost of producing F1 hybrid tomato seed.

2. To stop the setting of fruits on a commercial tomato crop when the
grower realizes that the plants have already set as many fruits as they can
properly size, field and market circumstances considered.

In this trial, three concentrations of Zerdok applied by spraying on April 23
and April 27 are under study. Five-plant plots at each concentration were
sprayed to run-off on both dates in order to have examples of heavier doses
of the systemic chemical. Much more testing will be required before feasi-
bility of the use of Zemdok on tomato can be determined.

POLE BEAN BREEDING (In coop. with Dr. A. P. Lorz and Dr. R. A. Conover)

The yield-trial planting is very late because it has to be replanted on
March 20. SES #1 and #2 are marked for those interested to see them in the
young stage.

The most encouraging items in the crop are two F2 stocks, most of the
plants from original seeding of February 23, showing neatness, length, color,
and number of pods. These are:

61-3 Florigreen of S&M Selection X F-M 191.

61-7 = SES #2 X F-M 191.

Careful selection in these populations will be required for several seasons
to fix resistance to rust and other disorders.

Field 12 (E. G. Kelsheimer)

Purpose: To note the effectiveness of insecticidal sprays on several varieties of
tomatoes.

Seven varieties of Dr. Walter's selection were included in this test. It
has been noted that there is a definite varietal susceptibility to attack
from leafminer and also a definite response of the plant to treatment.
Varieties set 2/21/62.

Plants were set on Feb. 13, staked and hoed on Mar. 16, hoed again on
Mar. 30 and the herbicides were applied as directed sprays on Apr. 3.
Because weather conditions were so bad the treatments were made two
weeks later than desired.
