PEACH AND NECTARINE VARIETIES AND SELECTIONS AT MONTICELLO, FLORIDA IN 1966.

by H. W. Young1


The first peach and nectarine variety and breeding material plantings were
made at the Big Bend Horticultural Laboratory, Monticello, Florida, in February of
1964. Additional plantings were made in 1965 and in February 1966, the following
varieties were added to the variety tests: Tejon, M-49 ers, Bur-Elb, Nectar,
Flordaqueen, Red Cap, Valigold, Red Robin, Flamingo, Panamint, Silver Lode, June-
gold, Springtime, Double Delight, Saturn, Armgold, Bobolink, Cavalier, Blake,
Garden State, Red Skin, Red Chief, Lexington, Red Top, Coronet, Belle of Georgia,
Dixiland, Red Bud, Afterglow, Southland, Hiland, Santa Rosa and Loring.

Yields.- The 1966 peach records (summarized in Table 1) were taken on 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 1966. For example, a tree planted in February
1964 is listed as three 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 promin-
ent beak in some years,

Chilling Hours.- The number of hours of temperature at or below 45 degrees F.
in the winter of 1965-66 were: 377 before January 15; 659 before January 31;
786 before February 15; and 870 before February 28. There appeared to be suffic-
ient cold temperatures to satisfy the chilling requirements of all varieties.

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

Fertilization.- Approximately 1500 pounds per acre of 10-10-10 was broadcast
in the spring of 1966. Neutral Zinc was applied as a foliage spray.

Diseases, Insects and Spray Program.- Scab was present, but was not considered
serious. Bacterial spot was found on an occasional weakened tree. Frown rot was
a problem where harvesting was delayed due to wet wea a. Stink bugs and other
insects that cause misshapen fruit were at a low 1 urculio damage was not
found and only small isolated incidences of whi sc le were evident. The
spray schedule in NFES Mimeo Report 61-6 was his sp y program consists of
Parathion and Sulphur. Two applications t4 '4rin was app ed after harvest for
borer control. k ,AI
