摘要
应用灰色关联度分析法,对云南省1998—1999年度夏播油菜多点试验主要经济性状与产量的关联度进行分析,结果显示:夏播油菜主要经济性状与产量的关联序为单株生产力>植株高度>千粒重>每角粒数>单株有效角果数>分枝数。在夏播油菜品种选育中应注重对单株生产力、植株高度和千粒重这3个经济性状的选择。
A method of grey correlation degree analysis was applicated to analysis important economic characters and yield in 1998-1999 years summer sowing rape in Yunnan province. The results showed: The order of those correlation degree is productivity per plant, plant height, weight per 1 000 seeds, seeds per legumen, effective pod numbers and effective branching. The hight productivity per plant, plant height and weight per 1 000 seeds are more useful in summer sowing rape breeding.
