Sixty-five F_1 hybrids from Muscadine (Vitis rotundifolia) cv 'Summit' X 'Noble' were analyzed for the inheritance of flower sex, berry size and color. The segregation of flower sex followed the 1:1 Mendelian single gene ratio in perfect: female flowers. The color segregation followed 2:1:1 Mendelian ratio in black: red: bronze. These data indicate that the berry color is controlled by 2 pairs of independent genes. Berry size in 90 percent of the hybrids was confined within the size of their parents. Among those that were larger than parents, 85.7 percent were female flowers. This suggested that a large number of hybrids are necessary in order to select large fruited individuals with perfect flower in such a cross combination.
