Stability analysis of yield and its component traits in fenugreek germplasm

Abstract

Stability and sustainability index studies were performed in 55 fenugreek genotypes including four check varieties during rabi 2005-06 and 2006-07 at CCSHAU, Hisar; RAU, Pusa; NDUA&T, Faizabad and in rabi 2005-06 at NBPGR, New Delhi alongwith per se performance. The analysis of pooled data indicated highly significant differences among the genotypes and environments for all the traits. The variance due to genotype and environments were highly significant for all the traits. Highly significant pooled deviation for plant height, number of primary branches per plant, pods per plant, and seed yield per hectare and highly significant G * E (Linear) interaction for plant height, pods per plant, and seed yield per hectare indicated the preponderance of non-linear components of G * E interaction. The genotype IC144260 had shown consistent performance and stability in wider environments for seed yield per hectare and pods per plant, whereas IC144243 has shown consistent performance in poor environment for seed yield per hectare.
