Stability analysis of grain yield and its components of rice (Oryza sativa L.) genotypes

Author(s): R Eswaran, V Anbanandan
Abstract: Genotype x environment interaction was studied for grain yield and their component characters in twenty eight genotypes in three environments. The environment + (genotype x environment) was significant for all the characters indicating distinct nature of environments and genotype x environment interactions in phenotypic expression. The genotype x environment (linear) interaction component showed significance for all the characters studied. This indicated significant differences among the genotypes for linear response to environments (bi) behavior of the genotypes could be predicted over environments more precisely and G X E interaction was outcome of the linear function of environmental components. Based on stability parameters and over all mean, were stable in HB3319-2WX-6-3-1-B,IR47547-3B-26-2B-1,IR64419-3B-13-1,IR65192-4B-8-1,IR71833-3R-3-2-1-B,IR71895-3R-26-2-1-B,IR71999-3R-2-1-B andIR72046-B-R-3-1-1-B performance for grain yield.
