The inheritance of flower types and F1 survivals in a complex advanced breeding line of “N18-6” grape

Zhongbo Ren, Jiang Lu, Xia Xu

Abstract


1340 F1 hybrids of advanced breeding line N18-6 crossed with seven grape pollens were evaluated for survival and fl ower sex segregation in the fi fth year. The survival rates of the hybrids were ≈5% to 11%, ≈10% to 20%, and ≈56% to 60% with Vitis vinifera, Florida hybrids, and disease-resistant germplasm pollinations, respectively. Some male flower plants were observed among these female/perfect fl ower crossings, which indicated that the fl ower inheritance of grapes is more complicated than previous understood.
