摘要
用AMMI双坐标图分析2017年贵州省高海拔玉米区域试验。结果表明,其可以客观地评价参试品种与试点的互作关系,不但可以直观了解每个品种在各个区试点的丰产性、适应性,还可以了解品种对环境(试点)及环境对品种的特殊需求,为育种家制定育种目标提供重要的参考,为引种生产的稳定性、适应性提供科学依据。
The regional test of high altitude maize in Guizhou Province in 2017 was analyzed by AMMI double coordinate.The results showed that this method could objectively evaluate the interaction between the tested varieties and the experimental sites.We could not only intuitively understand the prolificacy and adaptability of each variety in the experimental areas,but also understand the special needs of the varieties for the environment(experimental sites)and the environment for the varieties.It could provide important reference for the breeders to formulate breeding objectives and provide scientific basis for stability and adaptability of introduction and production.
