Stability analysis for seed yield, components of seed and oil in linseed (Linum usitatissimum L.)

The genotype X environment interaction was studied for 10 parents and their 45 F₁s for seed yield and 8 quality traits in linseed under 4 environments. Highly significant differences among genotypes, environments and E+(G X E) interaction for all the characters were observed. The nonlinear component of G X E was significant for all the characters except protein and oil contents. G X E (linear) interaction was significant for all the characters except iodine value and palmitic acid. The variety T 397 for seed yield per plant and oil content, R 552 for protein content, R 17 for palmitic acid and K 2 for stearic acid was consideloid as stable. Cross combination T 397 X LCK 152 was stable for all the characters except stearic and oleic acids. No correlation was observed among the three stability parameters for quality characters. Thus it was concluded that all the three parameters should be taken into account for improvement in quality traits in linseed.
