【摘要】 利用河南省已审定和区试通过的26 个夏大豆品种,对主要农艺性状与产量的关系进行二次逐步回归筛选,确定了主要性状最高理论产量指标并模拟出高产指标,此两项指标可比当前高产对照豫豆8 号增产71-8 % 和30-0 % 。更多还原

【Abstract】 The stepwise regression method was used to study the relation between major agronomy characters and yield of 26 varieties which included 23 reliesed varieties in Henan Province.The study showed that around 110.5 day growing stage,0 scare SMV,less than 0.7 scare lodging,more than 54.2 pods per plant,around 27.9 g weight per 100 seeds and 0% rate of purple spot were best indexes to increase the yield in the future.The soybean yield could be 71.8% higher than the check variety if the best indexes were used.更多还原
