Stability analysis of yield and its component traits in coriander germplasm

Abstract

Stability analysis were done in 42 coriander genotypes including three check varieties during rabi 2010-11 and 2014-15 at TNAU, Coimbatore with 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 umbels per plant and seed yield per hectare and highly significant G × E (linear) interaction for pods per plant and seed yield per plant indicated the preponderance of non-linear components of G × E interaction. The genotype CS 245 had shown consistent performance and stability in wider environments for seed yield per plant, whereas CS 14 has shown consistent performance in poor environment for seed yield per plant.
