中国和欧洲大豆资源农艺性状综合性评价

Comprehensive Evaluation of Agronomic Characteristics of Soybean Resources in China and Europe

通过对158份中国和欧洲大豆材料的12个主要农艺性状进行分析,利用统计分析、相关性分析、主成分分析等方法对试验材料进行综合评价,结果表明,欧洲大豆材料中有10份材料生育期过长,无法完全成熟;平均株高、主茎节数、有效分枝数与国内大豆材料相比均较高,且有粗蛋白质和粗脂肪含量表现优异的材料。最终筛选出12份综合表现优异的材料,可在育种中使用。

The total of 12 main agronomic characteristics of 158 Chinese and European soybean materials were analyzed.Statistical analysis,correlation analysis,principal component analysis and other methods were used to comprehensively evaluate Chinese and European materials.The results showed that ten European soybean materials had too long growth period and could not mature completely.The average plant height,main stem section number and number of effective branches of European soybean materials were higher than those of domestic soybean materials,and there were materials with excellent crude protein and crude fat contents.Finally,a total of 12 materials with excellent comprehensive performance were selected for use in breeding research.
