摘要
应用灰色关联度原理对影响长绒棉产量的主导因素进行分析 ,结果表明 :长绒棉产量与各农艺性状之间关联度大小依次是 :667m2 株数 >铃数 >籽指 >衣分 >衣指 >生育期 >株高 >果枝数 >铃重 >不孕籽 ,为选育优良新品种提供科学依据。
Main factors affecting yield of sealand cotton are analysed with the way of Gray Relational Grade.The results indicates that the Gray Relational Grade among yield of sealand cotton and agronomic characteristics in sequence from the biggest to the smallest is plants/667 m 2,bolls,seed index,lint percentage,grow stage,plant height number of fruit branches,boll weight and sterile seed,which gives scientific basis for breeding new variety.
