| Abstract | ||||
| Thirteen hybrids of tomato and their parents were evaluated to yield and its components as well as to the relative susceptibility B. tabaci infestation. The experiments were conducted at EL-Gemmeza Agriculture Research station, Gharbia Governorate during 2001 and 2002 in summer seasons. The results indicated that,Super Strain B cultivar produced the highest early and total fruit yield. While cherry cultivar produced the lowest early and total fruit weight. F1 hybrids produced more early and total yield than their parents. Chico Π cultivar was the most susceptible to B. tabaci infestation. However, Mobil cultivar was the most tolerant cultivar to B. tabaci infestation. Hybrid plants were tolerant to B. tabaci infestation than their parents. GCA and SCA were highly significant for all studied traits, suggesting that both additive and non-additive genetic variances were important. However non-additive gene effects were more important than additive gene effects for the inheritance of all studied traits. The cultivars Tallalakheen, Money Maker and Chico Π were good combiners for early and total fruit yield. | ||||
