TOMATO VARIETAL RESISTANCE TO LEAFMINER

Purpose; To note the tolerance or resistance to leafminer attack and the effective-
ness of insecticidal sprays on fourteen varieties of tomatoes, Fourteen
of Dr. Walter's selections were included in this test, It has been no-
ted that there is a definite varietal susceptibility to attack from leaf-
miner and also a definite response of the plant to treatment.

after. Very light leafminer infestation.

Field 6 (J. M. Walter)

POLE BEAN BREEDING

(in cooperation with Drs, P. P. Lorz, M. 0. Thomas and R. A. Conover)

These plots, seeded on March 6, have suffered considerable damage from
wind and unsolved nutritional imbalances. The standard varieties and advanced
selections from the back-crosses to F-M 191 made in 1961 by Dr. Lorz are under
comparison in the south half of the planting. In the northern half of the area
practically all of the selections under observation are new types of beans from
recent crosses made by Dr. Lorz. Several are from matings that involve bean
stocks far removed from the commercial stocks important in Florida, including
Scarlet Runner and P.I. accessions reported to be resistant to such troublesome
diseases as bacterial blight, Rhizoctonia and southern bean mosaic. Work with
these new types is thus purely exploratory.

GCS TOMATO EVALUATION TRIAL: Regular Vine Type

Purpose: Evaluation of GCS advanced breeding lines which are considered potential
new varieties compared with Manalucie and Manapal. Evaluations are made
on the basis of quality, yield, size of fruit, earliness and other
horticultural characters.

History: Seed were sown in flats containing sterilized soil on Jan. 7th. Seedlings
were transplanted to other flats on Jan. 20 and plants were set in the
field with ball of soil on Feb. 17. Row spacing is 4.5 feet and plant
spacing 12 inches.

Land was treated with VPM and 600 Ibs./A of 4-8-8 fertilizer was in-
corporated in the beds when made up. Fertilizer has since been added
on a weekly basis, beds were barred off two times and fertilizer banded
and covered. The third application at lay-by and just before staking
was at the rate of 1400 lbs./A. Subsequent applications of 400 Ibs./A
were applied on top of the ground and swept in lightly. A total of
approximately 3900 lbs. of 4-8-8 fertilizer per acre has been applied
to date.

Plants were pruned to 2 stems, one stem pruned to a single hand of fruit.
To provide sufficient cover to protect fruit, pruning was discontinued
when plants were about half grown.

Varieties:
1. Manalucie standard for vine ripe harvest.
2. Manapal good dual purpose variety, displacing Manalucie for vine
ripe.
3. STEP 430 Large fruited with resistance B E Rot, cat facing and
graywall as well as CAStW.

Field 11 (J. M, Walter)

TOMATO BREEDING
(in cooperation with D. G. A. Kelbert and several staff-members from other stations)


These plots, with a few exceptions, are from transplanting on Feb. 19 and 20
after seeding in raised beds on Dec. 30 and 31. The young transplants were rather
severely frosted on Feb. 24 and about 25% of the stand is from re-setting.

Many different kinds of tomatoes are included in the crop; and some have been
mistreated because, in trying to strike a happy medium in timing of applications of
fertilizer, it has been too late for truly early stocks, too early for late stocks.

Perhaps; the most interesting points and problems on which this crop now offers
convincing comparisons are as follows:

1. Early ar1 cornzentrated-yielding determinates

With the costs and troubles involved in harvesting tomatoes getting worse
each yea::, it is of great economic importance to tomato growers to have concen-
trated-yiclding stocks that will require not more than 2 pickings. This partic-
ular tomato-breeding effort has been pursued for 12 years now, and we have fixed
productive stocks such as STEP 410, STEP 458, and STEP 461 to show for it. Of
these 3 c:amples, only STEP 461 shows a good degree of earliness in combination
with concentrated yield and possibly all other traits required in a profitable
tomato-type for extensive ground culture in southern Florida. New possibilities
that eppear very promising can be seen as tagged plants in the row of 1033 CAStW
in F2.

A number of taxpayers in Florida are looking forward to the canning of high-
quality products from mechanically-harvested acreages. A short, stand-up type
of plant is required for this purpose. Numerous items on the field will show
you that we .::..lldo not know what to expect from most crosses and most selections
in length of plants in a season such as this. Dwarf types bred by Dr. Lorz as
a genetic study in anticipation of the current problem can be seen at the south
end of the field.

2. Handling Quality in Tomatoes Harvested Green and Ripened in Northern Terminals.

Quality of tomatoes in this respect has eluded us for many years; but there
is good reason to believe that we have learned, from experience of the past year,
how to select for the coloring and keeping features desired by those interests
shipping green tomatoes for ripening and repacking at the terminals. Chilling in-
jury is an important aspect of the problem, and growth of the saprophytic fun-
gus Alternaria tenuis is being used as the measure of this reaction. The major
effort of this season is being made upon ripening-room comparisons of our lines.
Two dozen of the latter are in the F3 from the cross between STEP 410 and Home-
stead 24, designated on the field as the "836" family; but none of these set
fruit as well in mid-March as was expected.

3. Catface

This disorder of unknown etiology is causing a rather high culling per-
centage on this crop. Since the recent trend of the market is to larger fruits
for the premium prices, there appears to be no further reason for hope that
the lesser hazard of loss to catface in smaller fruits, such as those of Flor-
alou, can be of much help to growers in Florida.

It has been apparent that fruits starting development this season during
two periods, March 15-20 and April 12-16, have been afflicted by this disorder.
These observations, and many more like them of past seasons, do not lead to
any helpful ideas on the problem.

4. Resistances to the DcrayFusarium

Effective resistance to this new biotype of the Fusarium wilt has now been
advanced by five generations of crossing with our largest-fruited stocks having
the greatest arrays of resistances to other diseases. Stocks representing this
stage of the procedure may be seen at the south end of mid-field (ex. 767-R1
CAStMld). From the best of these stocks, the effort will now be started to ob-
tain, by selection, highly productive lines, normal and determinate, that have
all the recessive resistances required by the vine-ripe growers of Florida.
This list of resistances is long and important because it includes growth-crack-
ing, graywall, blossom-end rot, etc.

5. New Dominant Resistance to Tobacco Mosaic

In August of 1963 a resistance to tobacco mosaic believed to be immunity
and to be controlled by a single dominant gene became available from the long-
term effort of Dr. L. J. Alexander of Ohio. Our experience to date with this
resistance indicates that it is effective. It is fixed only in unproductive,
semi-primitive breeding lines to date. These may be seen at the SW corner of
the field (ex. Alex. 62-2542-5-4). The effort to advance this resistance has
already been started in a back-crossing program. No time will be lost in try-
ing to combine this resistance with all the other features needed in tomato-
stocks for the vine-ripened phase of the industry in Florida.

CHEMICAL HERBICIDES ON SOUTHERN PEAS

Purpose: A test of preplanting and preemergence herbicides applied immediately be-
fore and after seeding (var. Cal. Blackeye No. 5)

History: Planted and treated on March 17. No. 7 (Check) plots were hoed on April 10.
The No. 1, 3 and 5 treatments gave good weed control but have been hoed
lightly to remove volunteer tomato plants which were not controlled.


Treatments:
1. Dacthal 10.3#1A.
2. Diphenamid 5_/A.
3. Tillam 3#/A. inc. preplant
5. Vegiben 5I/A.
