内蒙古区域试验小麦品种(系)籽粒产量AMMI模型分析

AMMI Model Analysis of Grain Yield of Wheat Varieties(Lines)in Inner Mongolia Regional Trials

为客观评价参加内蒙古区域试验(区试)小麦品种(系)的高产稳产性和适应性,探明适合其试验结果的分析方法,采用AMMI模型对2016-2020年参加内蒙古区试小麦品种(系)的籽粒产量进行分析。结果表明,环境差异是引起内蒙古区试小麦品种(系)产量差异的主要原因,且基因型与环境存在互作效应。结合籽粒产量和稳定性参数(D_(g))对品种(系)高产稳产性进行度量,筛选出农麦482、农麦300、赤麦8号和农麦016适宜内蒙古地区种植的高产稳产小麦品种(系)。通过分析内蒙古区试小麦品种(系)与试点互作效应值发现,农麦482更适宜种植在呼和浩特市玉泉地区,农麦300更适宜种植在达拉特旗树林召镇地区,赤麦8号更适宜种植在呼和浩特市玉泉区和赤峰市松山区,农麦016更适宜种植在通辽市钱家店镇地区。通过AMMI模型对内蒙古区试小麦品种(系)籽粒产量分析表明,AMMI模型可以客观地评价内蒙古小麦区域试验中小麦品种(系)的高产稳产性和适应性,为选择小麦优良品种及新品种适宜推广种植区域提供理论依据。

To objectively evaluate the high and stable yield and adaptability of wheat varieties(lines)participating in the Inner Mongolia regional trial,prove the analysis method suitable for Inner Mongolia wheat regional trial test results,the grain yield data of wheat varieties(lines)participating in the Inner Mongolia regional trial from 2016 to 2020 were analyzed using AMMI model.The results showed that environmental differences were the main reason for the yield differences of wheat varieties(lines)in the Inner Mongolia regional trial,and there was interaction between genotype and environment.By combining the two indicators of grain yield and stability parameter(D_(g))to measure the high yield and stability of varieties(lines),Nongmai 482,Nongmai 300,Chimai 8 and Nongmai 016 were the high yield varieties suitable for Inner Mongolia.By analyzing the interaction effect values of wheat varieties(lines)in the regional trials in Inner Mongolia and the pilots,it was found that Nongmai 482 is more suitable for Yuquan district,Hohhot,and Nongmai 300 was more suitable for Shulinzhao town,Dalad banner,Chimai 8 was more suitable for Yuquan district,Hohhot and Songshan district,Chifeng,and Nongmai 016 was more suitable for Qianjiadian town,Tongliao.The analysis of the grain yields of wheat varieties(lines)in the Inner Mongolia regional trials by the AMMI model was proved that the AMMI model could objectively evaluate the high yield stability and adaptability of wheat varieties(lines)in Inner Mongolia wheat regional trials.The results can provide the theoretical evidence for breeders to choose good varieties and areas suitable for popularization planting of new wheat varieties.
