Standard breeding methods are being used in this breeding program. Methods involve selecting accessions having the most desirable combination of characters, hybridizing those accessions, and selecting the most elite offspring and testing them as potential varieties. Breeding efficiency is enhanced through the standard use of embryo culture to produce progenies from seedless x seedless crosses. Advanced selections are tested in demonstration plots to determine commercial potential relative to competing cultivars. Powdery mildew resistance will be incorporated into high quality table grape germplasm through direct hybridization. Selection for powdery mildew resistance in appropriate progenies will initially occur in the greenhouse at the seedling stage. Powdery mildew resistant seedlings will then be transplanted to field sites where fungicides are not used for further evaluation.
