title: Non-parametric estimation and component analysis of phenotypic stability in chickpea (Cicer arietinum L.).
abstract: In order to determine phenotypic stability and contribution of yield components in the phenotypic stability of grain yield 21 genotypes of chickpea were evaluated in a randomized complete block design with three replications under rainfed and irrigated conditions in college of Agriculture, Razi University of Kermanshah, Iran, across 4 years. Non-parametric combined analysis of variance showed high significant differences for genotypes and genotype-environment interaction indicating the presence of genetic variation and possibility of selection for stable genotypes. The genotype number 8 (Filip92-9c) with minimum Si(2) and Si(2) of yield stability and grain yield in one parameter also revealed that genotype Filip92-9c was the most desirable variety for both yield and yield stability. Component analysis using Ci-value displayed that number of shrub per unit area has the most contribution on the grain yield phenotypic stability.
