PEACH VARIETIES AND SELECTIONS AT QUINCY, FLORIDA, IN 1962

by H. W. Young
Assistant Horticulturist

Yields.--The 1962 peach records (summarized in Table 1) were taken on tree ripe fruit.
When comparing yields of any two varieties, age of tree must be considered. The age of
tree listed in the table is the number of years the tree has been in the orchard and
includes 1962. As an example, a tree planted in February 1956 would be listed as seven
years of age.

Fruit Characteristics.--At each harvest ten representative sound fruit were measured
and these measurements averaged at the end of the season for each tree and variety (Table
2.) The beak or point at the end of the fruit, even thought quite small, is listed because
some varieties exhibit a tendency to have a prominent beak in some years. Split pits were
present in 1962 but no so prevalent as in 1961. An extended April and May drought reduced
fruit size of May and early June harvests.

Chilling Hours.--The number of hours of temperature at or below 45 degree F in the
winter of 1961-62 were: 666 before February 15; 668 before February 28; 760 before March
15; and 782 before March 31. There appeared to be sufficient cold temperature to satisfy
the chilling requirements of all varieties. A low of 27 was recorded on March 6.

Thinning.--Very little thinning was done in 1962 because a late cold period occurred
after most varieties had set fruit. Some fruit set after the cold and the flowering period
extended over a long period so that the size of young fruit was quite variable. Rather
than risk overthinning it was decided to take the alternate risk of underthinning. Under-
thinning resulted in several varieties maturing too many fruit which reduced fruit size
considerably.

Fertilization and Cultivation.--Approximately 1,000 pounds per acre of dolomite lime
was broadcast on January 26, approximately 1,000 pounds per acre of 10-10-10- ast
on February 12, and approximately 400 pounds per acre of ammonium nitrate 4,6i 'on
July 15. All applications were made on a tree basis and the fertilizer -'~:-i for e
tree. i

Diseases, Insects and Spray Program.--Scab was the most prevalent 'se
however, it was less of a problem than in 1961. July harvests had some scattered scab
lesions on the fruit. Bacterial spot was not identified. Brown rot was ent in
but was not a real problem. Stink bugs and other insects that might cause s i/its
were at a low level. Curculio damage was not found and there was no evidence e. A
total of 16 sprays were made from February 8 to July 23. Parathion and sulphur were the two
materials used. (See spray schedule in NFES Mimeo Report 61-6.) The timing of the sprays
are very important especially for the control of insects and scab. Three or four late
summer trunk sprays will be applied in July, August and September for borer control.

Recommendations.--Maygold still appears to be the most dependable variety for the
early shipping market. Earligold and Junegold are suggested for limited planting because of
their earliness and fruit quality. Hiland and Sunhigh have excellent fruit quality but
their higher chilling requirements make them unsuitable for commercial consideration.
Flordaqueen appears suitable for home garden production, however, its rapid ripening and
softness would make shipping risky. Suwannee has fine quality fruit; however, it is too
late for the early market.
