冀中南棉花产量品质性状的相关及通径分析

以2005-2012年河北省及国家黄河流域棉区审定的57份棉花品种为试验材料,在冀中南棉区（河北深州）设置品种比较试验对供试材料的12个主要性状进行变异性、相关性和通径分析,以期为冀中南棉花品种选育及应用推广提供理论依据。结果表明：考察的12个性状中以单株铃数、皮棉产量和纤维伸长率的变异系数较大,分别为9.89%、9.07%和11.43%。皮棉产量与单株铃数、单铃重和衣分的相关系数和直接通径系数均较高,表明单株铃数、单铃重和衣分对皮棉产量的贡献较大。皮棉产量与上半部平均长度、整齐度指数、断裂比强度、马克隆值呈正相关,且与断裂比强度的相关性达显著水平。产量与品质性状间的负相关性逐渐减弱,产量与品...

Summary:以2005-2012年河北省及国家黄河流域棉区审定的57份棉花品种为试验材料,在冀中南棉区（河北深州）设置品种比较试验对供试材料的12个主要性状进行变异性、相关性和通径分析,以期为冀中南棉花品种选育及应用推广提供理论依据。结果表明：考察的12个性状中以单株铃数、皮棉产量和纤维伸长率的变异系数较大,分别为9.89%、9.07%和11.43%。皮棉产量与单株铃数、单铃重和衣分的相关系数和直接通径系数均较高,表明单株铃数、单铃重和衣分对皮棉产量的贡献较大。皮棉产量与上半部平均长度、整齐度指数、断裂比强度、马克隆值呈正相关,且与断裂比强度的相关性达显著水平。产量与品质性状间的负相关性逐渐减弱,产量与品质的同步改良取得一定成效。

Fifty-seven cotton varieties authorized by Hebei province or the Yellow River Basin during 2005- 2012 were selected as test materials, and their 12 main characters were studied through a variety comparative experiment conducted in Shenzhou city of Hebei province by using variation, correlation and path analyses. The purpose of this study was to provide a theoretical basis for the breeding and application of new cotton varieties in middle-south area of Hebei province. The results were obtained as follows ： among 12 characters, the variation coefficients of boll number per plant, lint yiel
