The effect of grafting on pollen fertility and seed production of diploid interspecific hybrid and tetraploid eggplant genotypes

Solanum melongena is susceptible to diverse diseases and parasites, in particular the wilts (bacterial, Fusarium Verticillium), nematodes, some insects. torvum robust Verticillium bacterial root-knot nematode. It was reported that interspecific hybrid plants originated out of hybridization these species were sterile. In our previous studies have been carried overcome this barrier, only from Faselis F1 used as female parent, many seeds obtained 9.07% grew into vitro. The percentage pollen viability germination tetraploid (amphidiploid) genotypes produced by vitro colchicine treatment, 6.8 3.4 fold its source diploid genotype, respectively. However, increment not high enough barrier between S. melongena. study, changes fertility hybrids plants, which grafted on Pala or , investigated. Pollen affected grafting, although they increased significantly (51.54% 119.73%, respectively) grafting. determined fertile rootstock for chromosome doubling cultured eggplants could increase number per fruit. concluded varieties can be rootstocks order viability, rate seed yield with low cultivated eggplant doubling.
