| Abstract | ||||
| This investigation was carried out at Sakha Agricultural Research Station Farm, Kafr El-Sheikh, Egypt. Seven faba bean (Vicia faba L) cultivars and/ or varieties were used as parents, sown and crossed with each of half diallel set giving a total of 21 crosses under insect free cages. The resulted F1,s along with their parental genotypes were sown in a complete randomized block design with three replications during 2016 /17 season. Griffing approach (1956) was used to estimate general and specific combining ability effects. The results pointed out that additive and non-additive nature of gene action were involved in controlling the inheritance of all studied traits. The ratio of GCA/SCA mean squares was higher than unity for flowering date, number of branches/plant , 100-seed weight and EC of seeds, while the same ratio was less than unity for plant height, number of pods/plant , number of seeds/plant, seed yield /plant and protein percentage. The parental varieties; Giza40 and Line1 considered as good source for yield improvement, while the parental varieties; Giza 429 and Maghreby1 considered as good combiners for improvement of earliness and yielding ability. The crosses; Ohishima-Zaira x Giza40, Ohishima-Zaira x Line1, T.W x Line1, Line 1x Sakha1 and Sakha1x Maghreby1 expressed highly significant inter and intra-allilic interactions in desirable direction for the traits in view. The crosses; Ohishima-Zaira x Giza40, Giza429 x Giza40, T.W x Ohishima - Zairai, T.W x L1 and T.W x Maghreby1 exposed significant better parent heterosis for most studied traits. Progenies of these crosses could be used in the segregating generations with application of bulk method to regenerate pure line(s) characterized by high yielding potentiality and high protein content. | ||||
