适宜河西走廊大豆玉米复合种植的大豆品种(系)筛选与评价OA
Screening and Evaluation of Soybean Varieties(Lines)Suitable for Soybean-Maize Intercropping in the Hexi Corridor
为了筛选适宜河西走廊大豆玉米带状复合种植模式的大豆品种,对26份大豆品种(系)相关农艺性状进行了测定,运用熵权法和灰色关联分析进行了综合评价.结果表明,株有效分枝数的变异系数最高,为 48.5%,其次为株高和株粒数,大豆产量与株粒数关联度最高;综合评价表明,大豆品种(系)倒伏情况的权重最高,为0.242,其次为株高(0.121),供试大豆品种(系)综合评价前5 及其加权关联度分别为中黄30(0.790)、陇豆661-8020(0.742)、长农 42(0.729)、陇豆 7号(0.712)和陇豆6221-15(0.709),这些品种(系)可作为筛选和培育适宜大豆玉米复合种植的大豆品种(系).
To screen soybean varieties suitable for soybean-maize strip intercropping in the Hexi Corridor,26 soybean varieties(lines)were evaluated based on agronomic traits.A comprehensive evaluation was conducted using the entropy weight method and grey relational analysis.The results showed that effective branches per plant had the highest coefficient of variation(48.5%),followed by plant height and grain number per plant.Yield was most strongly correlated with grain number per plant.The comprehensive evaluation indicated that lodging had the highest weight(0.242),followed by plant height(0.121).The top five soybean varieties(lines)based on weighted grey relational grade were Zhonghuang 30(0.790),Longdou 661-8020(0.742),Changnong 42(0.729),Longdou 7(0.712),and Longdou 6221-15(0.709).These varieties(lines)are suitable candidates for selection and breeding in soybean-maize intercropping systems.
