Abstract
[Objective]To screen high-yield and high-quality soybean varieties suitable for planting in Ankang area of Shaanxi.[Method]Va-riance analysis,correlation analysis and cluster analysis were used to evaluate the comprehensive performance of agronomic traits,such as plant height,number of pods and seeds per plant in 13 soybean cultivars.[Result]The yield of soybean had a strongly and notably positive correlation with the first branch height,plant height,pods per plant,seeds per plant and seed mass per plant under the same cultivation condi-tions.13 summer soybean varieties were clustered into five groups.Chuannongxiadou 3 and Zhonghuang 13 were clustered into group 1 and 3,respectively.Group 2 included two cultivars of Youchun1024 and Baodou 1519.Group 4 included four cultivars of Qindou 2017,Zhonghuang 39,Jindou 228 and Handou 15.Five cultivars,such as Qihuang 34,Qindou 2018 and Shaandou 125,Andou 203,chuandou 155 were clustered into group 5.[Conclusion]Of all the varieties tested,Qihuang 34,Qindou 2018,Shaandou 125,Andou 203 and Chuandou 155 could be pro-moted as the main planting varieties in Ankang area.In addition,the two varieties of Youchun 1024 and Baodou 1519 were suitable to be plan-ted in Ankang area as long as the plant spacing was well controlled and reasonable technical measures were taken to prevent plant lodging.关键词
