湖北栽培大豆产量及蛋白质含量与主要农艺性状的灰色关联度分析

Grey Correlation Analysis of Yield and Protein Content with Main Agronomic Traits of Cultivated Soybean in Hubei Province

采用灰色关联度分析法,对湖北省近年来推广种植的8个大豆栽培品种的产量、蛋白质及主要农艺性状进行分析,结果表明:大豆品种产量与有效分枝、单株粒重、单株荚数、株高和主茎节数的关联度高,与百粒重、生育期、蛋白质含量关联度小;大豆蛋白质含量与百粒重的关联度最大,与株高的关联度最小。

The yield and protein content in relation to main agronomic traits of eight soybean cultivarsplanted in Hubei Province were analyzed by grey relational analysis.The results showed that the yield ofsoybean varieties had a high degree of correlation with productive branches,seed weight per plant,podnumber per plant,plant height and node number,and had a poor correlation with hundred seed weight,growth period,and protein content.The correlation between protein content and hundred seed weight wasthe highest,while the correlation between protein content and plant height was the lowest.
