Genotype x Environment Interaction in Rice (Oryza sativa L.)

摘要

Genotype x environment interaction was studied for grain yield and its component characters in 15 genotypes of rice under six environments during kharif 2005 and 2006. Pooled analysis also indicated highly significant differences among the genotypes and environments for all the characters under study. The environment+(genotype x environment) was significant for all the characters indicating distinct nature of environments and genotype x environment interactions in phenotypic expression. Based on stability parameters and overall mean, performance genotypes Pusa Basmati-1, PR-114 and Sahib-140 were found promising with stable performance for plant height, effective tillers/plant and grain yield/ plot.
