摘要
采用灰色关联度分析法,对河北省近年审定的18个夏大豆品种的产量及主要农艺性状进行了分析。结果表明:大豆品种产量与各农艺性状的关联顺序为生育期>脂肪含量>株高>倒伏>病毒级>单株荚数>百粒重>分枝数>蛋白质含量。
The yield and main agronomic characters of eighteen approved soybean varieties in Hebei Province were analyzed using grey correlation degree analysis. The results showed that the yield was influenced by multiple factors, and the influence degree in order was growth period 〉 content of fat 〉 plant height 〉 lodging 〉 virus class 〉 pods per plant 〉 100-seed weight 〉 branch number 〉 content of protein.
