Genotype-Environment interactions in rice (Oryza sativa L.) in temperate region using the Joint Regression Analysis and AMMI methods

The objectives of the present study were to evaluate the genotype-environment interaction (GxE) in a temperate region of rice (Oryza sativa L.) using a low number of environments and to compare the Joint Regression Analysis (JRA) and AMMI (additive main effects and multiplicative interactions) metho...

Description
Summary:The objectives of the present study were to evaluate the genotype-environment interaction (GxE) in a temperate region of rice (Oryza sativa L.) using a low number of environments and to compare the Joint Regression Analysis (JRA) and AMMI (additive main effects and multiplicative interactions) methods in the quantification of GxE. Grain yield (GY) of commercial genotypes and inbreed lines of rice sowing in Argentina were used. GxE and the environment sum of square (SS) was highly significant (p
