Abstract

A set of 42 diverse genotypes of fenugreek (Trigonella foenum-graecum L.) was studied for stability analysis for grain yield and its components over four environments. The pooled analysis of variance revealed that the mean square due to genotypes were significant for all the traits studied except branches per plant. Environment wise analysis of variance was significant for all the traits in all the environments. Genotype x environment interaction was significant for all the characters except branches per plant and pod length. Environment + (variety x environment) component was significant for most of the traits. Mean seed yield was linearly influenced by the environment it was lowest in the most unfavorable environment. The test weight and branches per plant was least affected by environments. Considering all the characters the genotypes UM-36, RMt-303, UM-4 and UM-30 were found stable for seed yield.
