Abstract:In this study, we evaluated the stability and adaptability of winter wheat varieties using the additive main effect and multiplicative interaction(AMMI) and genotype main effect(G) plus genotype-environment(GE) interaction(G+GE) biplot models in Hebei province from 2009 to 2010. The results showed that the yields of the tested varieties were significantly different in genotypes, environments, and the interaction between genotypes and environments(P<0.01). SX653 and ND399 were two varieties with outstanding comprehensive performance in Hebei north central water group and south-central water group, respectively. while HN5840, WF6728, KN1006, and YB66180also performed well. Therefore, the comprehensive application of the AMMI model and GGE biplot can more intuitively and conveniently analyze and evaluate the high yield, stability and adaptability of the tested varieties and discrimination of the pilots.
