Abstract: An additive-dominance genetic model of genotype-environment interactions and corresponding statistical analysis were applied to analyze genotype-environment interactions of heterosis of leaf stay-green among six parents and their 15 F1 under four different environmental conditions.The results indicated that there were significant genotype-environment interactions of heterosis of leaf stay-green in maize F1.Different phenotype of heterosis of leaf stay-green had been found in the same environmental conditions among different maize hybrid crosses as well as the same cross under four different environmental conditions.The maize inbred line Shen137 was better material for breeding stay-green maize.

Key words: Maize, Stay一green, Heterosis, Environment interaction
