Abstract

Additive main effects and multiplicative interaction (AMMI) model has obvious advantages of analyzing the interactions between genotypes and environment, and it can describe the differences in the stability of genotypes and the discriminability of genotypes in different locations quantitatively. The prolificacy and stability of three pilots and seven genotypes were analyzed for the north state recommendation trial of Chinese flue-cured tobacco in henan province with AMMI model. The genotypes 9808, LJ981, Y101 had high and stable yield and value with wide adaptability. Y8342 had high yield and value, but with poor stability. The yield and value of CF222 were lower than the control NC89, but its stability was inferior to the control; the output value of LJ237 was higher than the control, while the yield and stability were inferior to the control.

Key words: Additive main effects and multiplicative interaction (AMMI) model, genotype × environment (GE) interaction, multiple regression, flue-cured tobacco.
