双标图法对大豆品系和试点的评价及各农艺性状相关性的分析

GGE-biplot Evaluation on Soybean Lines Adaptability and Testing-Site Representativeness and the Correlation Analysis between main Agronomic Traits

采用GGE双标图法对2009年8个试验地点种植的24份大豆材料进行了分析。结果表明:单位面积产量与单株荚数、单株粒数、单株粒重、百粒重之间存在正相关,与无效节呈负相关;AN2是一个既高产又稳产的品系;D和F试点既具有代表性又具有较强的鉴别力。

GGE-biplot method was used to analyze the data of 24 soybean lines from eight trial sites in 2009. The results showed that the yield per unit area had positive relation with pod number per plant,grain number per plant,grain weight per plant and 100-grain weight, and negative with number of null node. AN2 had higher yield and better yield stability than other lines. ＂D＂ and ＂F＂ testing-sites of Heilongjiang province were the best representative testing sites with better discrimination than other sites.
