Study on Genotype X Environment Interaction of Seed Yield, Oil Content, Fatty Acid Profile and Stability Analysis of Yield Related Trait in Linseed (Linum usitatissimum L.) in North Western Ethiopia
Cherinet Alem and Tadesse Dessalegn

Abstract:
Linseed (Linum usitatissimum), or common flax, is a useful plant that has been cultivated for thousands of years. Its oil is rich in omega-3 fatty acids, especially Alpha-Linolenic Acid (ALA) (C18:3) that was beneficial for heart disease, inflammatory bowel disease, arthritis and a variety of other health conditions. Nine linseed (Linum usitatissimum L.) genotypes were evaluated in randomized complete block design with three replications during 2011 main cropping season at six locations to determine the pattern of genotype by environment interaction of yield and yield related traits to identify the most stable linseed genotypes for wide and/or narrow adaptations. Combined analysis of variance (ANOVA) indicated significant variations among environments and among genotypes, indicating the existence of variability among the tested genotypes. Debark was the most suitable environment for seed yield, oil content, oil yield and most important fatty acid alpha-linolenic acid. Genotype by Environment Interaction (GEI) was statistically significant only for days to flowering, days to maturity and seed per capsule, indicating the importance of stability analysis. Additive main effect and multiplicative interaction (AMMI) stability analysis in this study selected Kulumsa-1 as stable genotypes for seed per capsule. Linseed adapts to North West Amhara Region, Ethiopia although differences were observed among genotypes. According to the combined analysis of variance for seed yield, oil content, oil yield and alpha-linolineic acid variety Kulumsa-1 can be used for wider cultivation to the North West Amhara Region, Ethiopia.
