Assessment of Stability Parameters in Linseed Genotypes

An experiment was conducted in linseed during the rabi of 2022-23 with the aim was to assess the stability parameters of yield and related traits. It is important to screen and identify the stable and widely adoptable genotypes in respect to yield and yield contributing characters, which could perform uniformly under different environmental condition. Seven genotypes, along with three checks, were evaluated in three different environments with three replications each. Analysis of variance was performed for seven traits: days to 50% flowering, number of branches plant-1, plant height, number of capsules plant-1, root volume, seed yield plant-1, and seed yield plot-1. The results indicated significant differences for all traits in all six environments, suggesting randomness and diversity in agro-climatic conditions. Furthermore, significant mean squares due to environments were observed for all traits, reinforcing the distinctiveness of the selected environments. The interactions between genotypes and environments were found to be significant for all traits. Notably, genotype BAU 2021-06 secured the second position in seed yield and demonstrated stability in seed yield plant-1, seed yield plot-1, root volume, and the number of branches plant-1. In contrast, genotype NL 371 claimed the first position in seed yield and exhibited stability in the number of branches plant-1, number of capsules plant-1, root volume, seed yield plant-1, and seed yield plot-1.
