AB <p>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 &times;environment interactions. Parametric and non- parametric stability statistics introduced genotypes: G13, G15 and G18 as the most stable. The statistics<img src="https://archives.thejaps.org.pk/Volume/2017/27-04/abstract/30_clip_image002.gif" width="18" height="26">,&nbsp;<em>bi</em>,&nbsp;<img src="https://archives.thejaps.org.pk/Volume/2017/27-04/abstract/30_clip_image004.gif" width="26" height="28">and&nbsp;<img src="https://archives.thejaps.org.pk/Volume/2017/27-04/abstract/30_clip_image006.gif" width="28" height="28"> were desirable for the simultaneous selection of yield and stability. Spearman's rank correlation indicated that most non-parametric measures were significantly (P&lt;0.01) inter-correlated with parametric measures and therefore can be used as alternatives.</p>
