基于AMMI模型的花生新品种区域试验分析

Analysis of New Peanut Variety Regional Trials on AMMI Model

为进一步了解国家北方片花生新品种多点试验中小粒花生新品种的高产、稳产潜力以及各试点鉴别力,本研究以2019年国家北方片花生多点试验中小粒二组花生品种的荚果产量为依据,运用AMMI模型对11个花生品种在18个试点的荚果产量进行分析,结果表明,品种间、试点间、品种与试点间互作、交互效应主成分值(IPCA)均达到了显著差异,且IPCA1、IPCA2、IPCA3共占互作效应的71.36%。在参加试验的11个品种中,丰产性前3位的品种依次为:冀农花16号、开农111、漯花22号;稳产性前3位的品种依次为:花育20号、漯花22号、商花588;高产稳产前3位的品种依次为:冀农花16号、漯花22号、商花588。18个试点中鉴别力前3位的试点依次为:山东菏泽、河南漯河、河南驻马店;鉴别力较差的试点为:辽宁锦州、河北保定、河南濮阳。

For further understand the high-yield and stable yield of small-seed peanut varieties in north china,this study used the AMMI model,analyzed the pod yield of 11 varieties at 18 sites in the 2019 northern peanut regional test.The results showed that peanut varieties,test sites,the interaction between varieties and test sites,and the principal component value of interaction effect(IPCA)all reached significant levels of difference,and IPCA1 and IPCA2,IPCA3 together accounted for 71.36%of the interaction effect;among the 11 varieties participating in the experiment.The top 3 high yield varieties were:Jinonghua 16,Kainong 111,Luohua 22.The top 3 stability varieties were:Huayu 20,Luohua 22,Shanghua 588.The top 3 high and stable yield varieties were:Jinonghua 16,Luohua 22,Shanghua 588.The top 3 discriminators among the 18 sites were:Heze,Luohe and Zhumadian.The poor discriminators sites were:Jinzhou,Baoding and Puyang,
