Yield stability of chickpea genotype in environment condition

Abstract

Chickpea variety were evaluated using Randomized complete block design with three replications for estimating genotype x environment interaction (GEI) and yield stability of 10 genotype across six environments during 2015-2016 at Chhattisgarh. The objectives were to analyze yield stability of chickpea genotypes performance under Chhattisgarh conditions. Several statistical analyses were conducted:: Coefficient of Variance (CVi); Wricke’s Eco valence parameter (Wi); Lin and Binns cultivar performance measure (Pi); Finlay and Wilkinson’s regression coefficient(bi); and Shukla’s stability variance parameter . RG 2009-11 and Vaibhav© are the stable genotype according to the ranking order of the different method i.e. Shukla’s (1972), Wricke’s (1962) eco valence. JG 16 was ranked first on mean yield, also most stable genotype. According to Lin & Binn’s, JG 14 were unstable.
