This study analyzed the yield data of tested varieties in the 2017 Hubei rape regional trial by the AMMI model of GenStat Version 18.1 and GGE biplot, to comprehensively evaluate the yielding ability and stability of tested varieties, as well as the discriminability and representativeness of each test location. The results showed that, yields were significantly different for different varieties and test sites, and there was a very significant interaction between varieties and test sites. Shengguang168, Huayougao1, Huayouza702, Liyouza6 and Shengguang136 had better yielding ability, Liyou618, Huayouza9, Huayouza652, Yangguang160 and Huagaoyou1 had better stability. In variety adaptability, the variety Shengguang136 with better yielding ability and worse stability was suitable for planting in Xiaogan, Huanggang, Xiangyang and Zhongyousuo. Variety Shengguang168, Huayouza702, Shengguang136 and Huayougao1 had best comprehensive evaluation. In the functional form of the pilot, the pilots with better discrimination were Shayang, Qianjiang, Xiaogan and Yichang, the pilots with better representativeness were Huanggang, Zhongyousuo, Xiaogan and Suizhou, the pilots with better comprehensiveness included Xiaogan, Huanggang, Suizhou and Yichang. Comprehensive utilization of the AMMI and GGE biplot could provide reference for screening excellent varieties in suitable areas and offer an effective method and theoretical basis for screening new improved varieties with wide adaptability.
