Abstract:
Background: A suitable sunflower variety was developed with high yield and stability. Methodology: A total of eleven sunflower genotypes including the standard and local checks were evaluated at Finoteselam, North Achefer and Ayehu from 2010-2013 cropping season. Randomized Complete Block Design (RCBD) with three replications was used. Results: The results of variance analysis showed the significance of environmental variance compared to the genotype and GE interaction variances. Polygon view of GGE biplot revealed that X7 (Acc. 208768) was the genotype with the highest seed yield in five out of six environments. The Average Environment Coordinate (AEC) biplot showed that X7 (Acc. 208768) with the highest mean yield was a highly stable genotype as it was positioned close to the AEC abscissa. The biplot of comparison of the sunflower genotypes with the ideal genotype revealed that X7 (Acc. 208768) was the closest genotype to the ideal cultivar. Conclusion: Therefore, this genotype seems to be widely adapted across several environments and is released as an open pollinated variety for wider production in Western Amhara and similar agro ecologies.
