VARIATION IN FLOWER BUD NUMBERS ON RABBITEYE BLUEBERRY IN FLORIDA (VACCINIUM ASHEI READE) *

P.M. Lyrene
Twenty-four rabbiteye blueberry clones representing the "cultivated" gene pools in the breeding programs at Tifton, Georgia and Gainesville, Florida plus 22 native V. ashei clones selected from southeast Georgia and northeast Florida for fruit quality and early ripening were studied. Test plots were grown in Gainesville, Florida and scored for season of ripening, leaf health, and number of flower buds produced per flowering twig. Mean flower buds per twig ranged from 1.81 to 8.52 for the cultivated clones and from 1.90 to 9.00 for the natives. Differences among clones within each group were highly significant. In both the cultivated and the native groups, healthy leaves were positively correlated with high flower bud production (r2=0.44 and 0.25, respectively). The early-ripening clones in the cultivated group, most of which were developed in Florida, tended to produce an insufficient number of flower buds for a full crop.
