Genotype x environment interaction for biometrical traits in pigeonpea (Cajanus cajan L. Millsp.) under varying spacings

Abstract

Twenty eight genotypes of pigeonpea, which includes promising lines as well as randomly selected varieties were studied for their G X E interaction. The genotypes were sown in a three different environments were made available by three spacings at 60, 90 and 120 cm. .Pigeonpea genotypes BDN 2001-6, Phule T 11-39, JJ 65, GT 1, BSMR 736 and LRG 41 are considered to be more desirable ones, as they satisfied the criteria suggested by Eberhart and Russell (1966) for stability over three different spacings.
