Abstract: In order to screen and introduce soybean varieties suitable for planting in Datong area of Shanxi province, seven soybean varieties including three fresh soybean varieties and four common soybean varieties were used as test materials; seven main agronomic characteristics including seedling period, growth period, plant height, pod number per main stem, number of branches, pod number per main stem and 100seed weight, and three main quality characteristics, including protein content, fat content and soluble sugar content were detected and analyzed using correlation analysis, principal component analysis and comprehensive score evaluation. The results showed that all seven soybean varieties could mature normally in Datong area of Shanxi province, and the adaptability of each characteristics was good. The coefficient of variation of seed number per pod and pod number per main stem were 173 and 062, respectively. Lyu 75 had the characteristics of early emergence, short growth period and good taste, therefore it could be introduced to Datong area as vegetable soybean variety. Cuishandadou and Zhonghuang 35 had the characteristics of excellent agronomic and quality characteristics, therefore they could be introduced to Datong area as main soybean variety. Correlation analysis indicated that seedling period, plant height were significantly positively correlated with pod number per main stem. Protein content showed a significant positive correlation with soluble sugar content, while fat content showed a significant negative correlation with number of branches. Principal component analysis and comprehensive evaluation analysis showed that Cuishandadou, Lyu 75 and Zhonghuang 35 had the highest comprehensive score, therefore they were the best varieties suitable for introduction and planting in Datong area. This study provided references for breeding and production of soybean in Datong area of Shanxi province.

Key words: soybean varieties, quality traits, agronomic characteristics, correlation analysis, principal component analysis, adaptability

摘要： 为了筛选并引进适应山西大同地区种植的大豆品种，以3份鲜食大豆、4份普通大豆共7个大豆品种为试验材料，对不同大豆品种的出苗期、生育期、株高、主茎节数、分枝数、每荚粒数和百粒重共7个主要农艺性状和蛋白质含量、脂肪含量及可溶性糖含量3个品质性状进行相关性分析、主成分分析及综合得分评价分析，确定不同品种在山西大同地区的适应性。结果表明，参试的7个大豆品种在山西大同地区均可正常成熟，各个性状在当地的适应性较好。每荚粒数和主茎节数变异系数最大，分别为173和062；绿75出苗早，生育期短，口感好，可作为鲜食豆在当地引种；翠扇大豆及中黄35农艺及品质性状表现均优良，可作为当地普通大豆的主推品种。不同性状的相关分析表明，出苗期、株高与主茎节数呈显著正相关，蛋白质含量与可溶性糖含量呈显著正相关，脂肪含量和分枝数呈显著负相关。综上并结合主成分分析和综合评价分析结果可知，翠扇大豆、绿75、中黄35在大同地区的适应性最好。上述结果可为山西大同地区育种及生产提供参考。
