- Abstract
In order to compare parametric and nonparametric stability measures, and to identify high-yield and stable bread wheat genotypes, 20 accessions were grown in a randomized complete block design with 3 replications under 6 irrigated and dryland conditions. Combined analysis of variance (ANOVA) and Bredenkamp test indicated the presence of significant genotype Xenvironment interactions. Parametric and non-parametric stability statistics introduced genotypes: G13, G15 and G18 as the most stable. The statistics ∂[sub i][sup 2] , bi, S[sub i][sup (3)] and S [sub i][sup (6)] were desirable for the simultaneous selection of yield and stability. Spearman's rank correlation indicated that most non-parametric measures were significantly (P<0.01) inter-correlated with parametric measures and therefore can be used as alternatives.
