棉花品种主要数量性状与皮棉产量的灰色关联分析

摘要

Main quantitative traits and lint yield were analyzed by grey correlation analysis in new cotton variety . The re-sults showed that :the numbers of bolls per plant and ginning outturn were the bigger influence factors to lint yield . The influ-ence degree to lint yields of every factor was as follows :the number of bolls per plant > ginning outturn > pre - frost yield > the first node of fruit branch > single boll weight > fruit branch number > stem height > seed index.%　　通过运用灰色关联分析方法对国家棉花品种区域试验中的参试品种（系）邯郸点试验数据进行了主要数量性状与皮棉产量分析。结果表明：对棉花品种皮棉产量影响较大的因素是单株结铃数和衣分，各个因素对皮棉产量的影响程度依次为：单株结铃数＞衣分＞霜前花率＞始果枝节位＞单铃重＞果枝数＞株高＞籽指。
