Grapevine is one of the most important fruit crops in the world. A program for the producing new table and raisin grape cultivars was started with evaluation of 90 cultivars which ended up to selection of six superior seeded cultivars as female parents and four seedless cultivars as male parents. In this study, 381 progenies originating from 22 cross combinations were evaluated when they were five and six years old during 2006 and 2007. According to seed or seed trace fresh weight, progenies were classified into four classes including completely seedless, semi-seedless, semi-seeded and completely seeded. Average seed/seed trace weight (in four classes) were 10.88, 22.47, 33.59 and 48.55 mg, respectively. As a result, 42 genotypes (11%) were considered as completely seedless, 52 genotypes (13.6%) as semi-seedless, 92 genotypes (24.1%) as semi-seeded and eventually 195 genotypes (51.2%) as completely seeded. 相似文献
