基于BLUP和GGE双标图的大果型花生丰产稳产适应性分析

High Yield,Stability and Adaptability of Big-fruit Type Peanut Based on BLUP and GGE Biplot

为筛选高产、稳产、广适花生品种,本研究利用国家北方片大果花生区域试验数据,运用最佳线性无偏预测(BLUP)+基因型主效加基因型-环境互作效应(GGE)双标图评价品种的丰产性、稳产性、适应性和各试验点的区分力和代表性。结果显示,参试品种的原始数据和BLUP值之间存在多个差异,用BLUP值代表育种值更加准确,比原始数据结果更加可靠;漯河、青岛、济宁、石家庄、郑州、开封、潍坊等7个试验点的区分性和代表性较强;P09-2、开农172、青花1号等3个品种的丰产性、稳产性、适应性等排名均居试验前列。基于BLUP-GGE双标图对大果花生品种及其试验点进行评价,不但为大果高产花生品种的选择和应用提供参考依据,也为基因型和环境互作评价提供方法借鉴。

In order to select the peanut varieties with high-yield,stability and adaptability,best linear unbiased prediction(BLUP)and genotype main effect plus genotype-by-environment interaction(GGE)biplot were used to evaluate high-yield,stability and adaptability of peanut varieties tested and discrimitiveness and representiveness of test sites according to the data of regional experiment of peanut in northern China.The results showed that there were many differences between the original data and BLUP value of the tested varieties,and the BLUP value was more accurate and more reliable than the original data.The seven test sites had high discrimination and strong representation,for example,Luohe,Qingdao,Jining,Shijiazhuang,Zhengzhou,Kaifeng,Weifang and so on.The high-yield,stability and adaptability of P09-2,Kainong172 and Qinghua1 get ahead of the others in test sites.BLUP data and GGE biplot could be used for evaluation of big-fruit type peanut and test sites,of which the study could not only provide reference for the selection and application of high-yield peanut varieties,but also provide methods for the evaluation of genotype-environmental interaction.
