摘    要:研究了棉花皮棉产是与其植株性状的相关性。结果表明,衣分等12个性状与皮棉产量呈正相关,其中子棉产量和经济系数与之极显著相关,衣分与之显著相关;伏前桃等5个性状与之呈负相关。通径分析表明,对皮棉产量可直接选择的性状有衣分、株高、伏前桃、果枝数、侧根重、总秆重、总根重、秋桃、伏桃和果枝重;不能直接选择的性状有棉产量、经济系数、主茎重、主根长度、单铃重、主根重和10月10日前收获产量占总产量的百分率。在

关 键 词:陆地棉  皮棉产量  植株性状  相关  选择  棉花

Abstract:The correlativities between lint yield and the plant characters were studied in this paper.The research results showed that twelve characters incl uding lint percentage appeared positive correlation with lint yield.Among the twelves,seed cotton yield and economic coefficient were significantly correlated with lint yield at 0.01 level and lint percent age reached to significance at 0.05 level.Oppositely,other five characters including bolls per plant by July 15 appeared negtive correlation with lint yield.The path analysis indicated that the traits can be selected directly for improving lint yield are lint per centage,plant height,bolls per plant by July 15,fruit branches,lateral root weight,all stalk weight,all root weight,bolls per plant by septembers, bolls per plant by August 10 and fruit branch weight.Lint percentage was the most effect ive for improving lint yield among these characters,plant height,lateral roots weight and No.of f ruit branch were in the following races.
Keywords:Upland cotton  Lint yield  Plant character  Correlation  Selection
