Abstract
The present experiment was carried out to assess the general combining ability (GCA) and specific combining ability (SCA) of seven important commercial cultivars of Vicia faba L. of faba bean and their 21 F1 and F2 generations. The data were analyzed using Griffing’s Model I Method II. Significant differences were found for all traits evaluated. Combining ability analysis of variance revealed significant differences for GCA and SCA effects among the parents and hybrids for almost all traits. The results suggested the presence of additive and non-additive gene action for almost all of the traits. The results (G.C.A) for seven parents revealed that the commercial variety Nubaria 3 had significant and positive G.C.A effects for 50% flowering, days to maturity and plant height, while the variety Giza 2 showed significant and negative G.C.A. effects for number of branches/plant, seed yield/plant, number of pods/plant and 100 seed wight. The good combiners for earliness was the parent Giza 716 and Giza 2, while for seed yield/plant and number of pods/plant was the parent Misr 3, But the parent Giza 843 was considered as the best combiner for number of branches/plant. Estimates of (S.C.A.) effects revealed that significant SCA effects were observed for some crosses. Moreover, the best combinations were (Nubaria 3 x Giza 2) for 50% flowering and number of pods/plant. (Giza 843 x Misr 3) for Days to maturity, seed yield/plant and wight 100 seed /plant. (Nubaria 3 x Giza 843) for number of branches/plant, (Sakha 3 x Giza 402) for plant height.. It can be concluded that possibility of use the superior crosses for improving faba bean traits by breeding processes and selection in sequent generations
