Genotype x Environment Interaction for Yield and its Components in Safflower (Carthamus tinctorius L.)

Sixteen promising genotypes including one check were evaluated under dryland condition during rabi 2012–13, 2013–14 and 2014–15 for the assessment of stability in seed yield and yield contributing traits of safflower. Variances due to genotypes and environment were significant for most of the characters while genotype x environment interaction was significant for seed yield, number of capitula/plant and number of seeds/capitulum. On the basis of performance and stability parameters, it was concluded that the genotype GMU-2724 was the most ideal, as this showed higher seed yield, number of capitula/plant along with number of seeds/capitulumand adaptability to wide range of climatic conditions. The genotype SSF-748 was other promising and suited to poor environment while genotype AKS-307 was also another most desirable and suited to high responsive environment. Consequent upon above findings the genotype GMU-2724 may berecommended as a variety for commercial cultivation in Jharkhand.
