PEACH VARIETIES AND SELECTIONS AT QUINCY, FLORIDA, I 963.

by H. W. Young*

Yields.- The 1963 peach records (summarized in Table 1) were takeei tree ripe
fruit. When comparing yields of any two varieties, age of tree should be considered. The
age of tree listed in the table is the number of years the tree has been in the orchard
and includes 1963. As an example, a tree planted in February 1956 would be listed as
eight 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 bottom end of the fruit, even though quite
small, is listed because some varieties exhibit a tendency to have a prominent beak in
some years. Split pits were more prevalent in 1963 than in 1962. 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 degrees F. in
he winter of 1962-63 were: 541 before January 15; 704 before January 31; 839 before
ebruary 15 and 986 before February 28. There appeared to be sufficient cold temperature
o satisfy the chilling requirements of all varieties. Lows of 24 on February 27 and 35
n March 23 resulted in the loss of fruit on the lower chilling varieties.

Thinning.- An effort was made to thin the fruit to at least 4 inches apart.

Fertilization and Cultivation.- Approximately 1,000 pounds per acre of 10-10-10
as broadcast on February 14. All applications were made on a tree basis and the fertilizer
weighed for each tree.

Diseases, Insects and Spray Program.- Scab was the most prevalent disease in 1963.
ruit of the varieties in the Maygold season, however, were free of the disease. Brown
ot was present in July. Bacterial spot was not identified. Stink bugs and other insects
hat might cause misshapen fruit were at a low level. Curculio damage was not found and
here was no evidence of scale. A total of 9 sprays were made from February 7 to June 13.
arathion 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 late summer trunk sprays will be applied in July, August and
september.

Recommendations.- Maygold still appears to be the most dependable variety for the
early shipping market. For the second year, Earligold developed its fruit under severe
brought conditions which resulted in fruit that was not suitable for shipping. Junegold
gain produced high quality fruit and if the grower does not object to split pits, this
riety is recommended for commercial consideration. At Quincy the split pits in Junegold
ave not materially detracted from the fruit's excellent appearance. Suwannee again produced
excellent quality fruit, however, it is somewhat late for early market consideration.

An interesting addition this year were two trees of the variety Bonanza, a true
warf tree.
