AMMI analysis of interaction of genotype and environment in chalkiness of indica rice

Chalkiness is an unpleasant trait for rice con-sumer. which is known to be controlled geneti-cally and affected by environment during grainmaturing. We used the model of Additive MainEffects and Multiplieative Interaction (AMMI)for interpreting the result of genotype by env-iornment interaction (G×E) in the chalkinessof indica rice varieties.
