| This study was conducted at Barrage Horticulture Research Station, Kaluobia Governorate, Egypt during the period from 2007 to 2010. The study started with F3 population of some plants selected frombroad bean F2 of the crosses Reinamora × Luzudo Otono, Reinamora × Akoadolz and Reinamora × Kassasein 7. The selection was done between and within the lines for the different characters by using pedigree selection. The characters studied i. e., plant height, number of branches/plant, total yield, pod length, pod thickness, weight of ten pods and seeds weight of ten pods. Coefficient of variance (C.V %) was estimated for nine F5 lines selected. From the results of the first season, four lines showed high homogeneity compared with the check cultivars, i.e. Reinamora and Kassasein 7. In the second season, four F6 lines were evaluated compared with the two above mentioned cultivars and estimated of phenotypic and genotypic coefficients variance (P.C.V % and G.C.V %) and broad sense heritability (BSH). The results showed significant differences between lines for different studied characters in both seasons. The lines 1-11, 1-45, 2-80 and 3-86 gave the lowest degree for C.V % for most studied characters. In the second season, all the breed lines significantly superior than the check cultivars for number of branches, total green yield and pod length. The results revealed high values of genotypic coefficient of variance (G.C.V %) and broad sense heritability (BSH %) for all studied traits. The values of G.C.V % ranged from 10.44 to 26.46 for pod thickness and weight of ten pods, respectively, and BSH % ranged from 70.70 to 91.89 for pod length and weight of ten pods, respectively, indicated that all traits were highly heritable and small environmental effects. It could be concluded that the lines 3-86, 1-45 and 1-11 are considered promising for releasing as new cultivars because they are homogeneous with high productivity and good pod characters. | ||
