Adaptability and Phenotypic Stability of Yield for Several Promising Large Seeded Chickpea Lines
Abstract: ABSTRACT

Twenty genotypes of large seeded chickpea were grown at five sites in Egypt over three years giving 5 environments. The phenotypic stability parameters suggested by (finlay and Wilkinson 1963) and (Eberhart and Russell 1966) were followed and genotype x environment ( G x E ) interaction was analysed using linear regression .
Predominance environmental effect, as a source of variance, was observed. This suggests the possibility of raising yield levels through improved management practices. There was also highly significant variation due to both genotypes and G x E interaction for seed yield. Line 110 and line 1922 were very desirable genotypes because their performance superior. As for line 110 b = 1.44, s²d = 0 with mean = 120.7% of grand mean whereas for line 1922 the stability measurements were, b = 1.43, s²d = 0 and with mean = 119.0% of grand mean. Those two breeding lines also considered stable for their earliness b = 1.00 and 1.12 and s²d = 0.40 and 0.47 for L.110 and L.1922, respectively. But L.110 flowered week earlier than L.1922.
