大粒花生品种区域试验的AMMI模型分析

AMMI Model Analysis on Regional Trials of Large-Seeded Peanut Varieties

运用AMMI模型分析了2015-2016年国家北方片花生区域试验荚果产量数据,结果表明,品种、试验地点、品种与试验地点互作、交互效应主成分值(IPCA)均达极显著水平。不同花生品种在各试验地点的稳定性和不同试验地点对品种的分辨力差异较大,开农705的稳定性参数最大(D g=32.9718),对照品种花育33号的稳定性参数最小(D g=11.3287);8个花生品种中高产稳产的品种是商花11号和郑农花15号,产量高而稳定性一般的品种是开农705和龙花二号,稳产但不高产的品种是花育33号;19个试验地点中山东日照和河南洛阳的分辨力强,河南漯河和安徽固镇的分辨力较差。

The AMMI model was employed to analyze the pod yield data of regional trials for large-seeded peanut from 2015 to 2016 in north China.The results showed that the varieties,test sites,the variety×test site interaction and the interaction principal component axis(IPCA)reached at extremely significant level.There were significant differences in stability of the eight peanut varieties and resolution of the nineteen testing sites.Among the eight varieties,the stability parameter of Kainong 705 was the highest(Dg=32.9718)and that of Huayu 33 was the lowest(Dg=11.3287);Shanghua 11 and Zhengnonghua 15 were the varieties with high-yield and high-stability,Kainong 705 and Longhua 2 were the varieties with high-yield and low-stability,Huayu 33 was the variety with low-yield and high stability.As for the nineteen testing sites,Rizhao in Shandong and Luoyang in Henan had the best resolution,while Luohe in Henan and Guzhen in Anhui were of lower resolution.
