基于AMMI模型的河南省小粒花生品种区域试验稳定性及适应性分析

Analysis of Stability and Adaptability of Small Peanut Varieties Test in Henan Province Based on AMMI Model

为评价小粒花生在河南省的稳定性、丰产性及不同地点的鉴别力,利用AMMI模型对2019年河南省小粒花生品种区域试验中的13个参试花生品种及8个试验地点进行分析。结果表明:g2(‘安花6号’)属于高产稳产型品种,g3(‘漯花19号’)属于高产较稳产型品种,适宜在河南省大面积推广种植。试点鉴别力方面,e6(河南新乡)、e2(河南洛阳)试点鉴别力较好,对品种的选择性强;e5(河南商丘)试点鉴别力较差,AMMI模型中的3个主成分值,共解释交互作用的85.87%,有效地分析了基因与环境间的互作效应。因此,可以利用AMMI模型对新品种稳定性、丰产性及适应性进行综合评价。

In order to evaluate the stability, high yield and discrimination of small-grain peanut in Henan Province, 13 peanut varieties and 8 test sites in the regional test of small-grain peanut varieties in Henan Province in 2019 were analyzed by AMMI model.The results showed that g2(’Anhua 6’) belonged to high and stable yield variety, and g3(’luohua 19’) belonged to high and stable yield variety, which was suitable for planting in Henan Province. In terms of discrimination, e6(Xinxiang, Henan) and e2(Luoyang, Henan)showed good discrimination and strong selection of varieties,e5(Shangqiu, Henan) had poor discrimination. The result showed that that three principal component in AMMI model could explain 85. 87% of the interaction effect, and the interaction effect between gene and environment could be effectively analyzed.
