Genotype by Environment Interaction and Stability Analysis in Sunflower Genotypes

The study was conducted during the main cropping season of 2019/2020 to evaluate advanced sunflower genotypes for its stability over multiple environments. The study was carried out at six locations namely; Holeta, Debrezeit, Fenoteselam, Arsi Negele, Kulumsa and Ambo. Randomized complete block design with four replication was used in layout of the experiment. Data were collected for seed yield and yield related components and subjected to analysis using R-software. AMMI and GGE-biplot were used to estimate the stability of genotypes across test environments. The results from AMMI analysis of variance showed that there is significant difference for environment, genotype and genotype by environment interaction for seed yield. AMMI analysis of variance for oil content revealed the significant differences for genotypes, genotype by environment interaction and non-significant for environment. The Gollob’s test showed that total variation greater than 70% was explained together by PC1 and PC2 for both seed yield and oil content. AMMI 1 bi-plot analysis for seed yield revealed that E1 and E5 was high seed yielder than others and genotypes, G4, G5 and G2 were stable genotypes relative to others. AMMI2 Bi-plot showed genotypes G3, G1, G6 and G8 were stable for seed yield whereas, G7, G8 and G1 were stable for oil content.
