本研究分析了国外高强纤维种质的若干经济性状的相关特征 ,表明纤维强度与长度存在较大的正向偏相关 (r偏 =0 1 81 ) ,麦克隆值与纤维长度呈显著负向偏相关 (r偏=(- 0 344 ) ;因此选择长、强、细纤维在实践上是可行的。但是纤维比强度与衣分存在显著负向偏相关 =- 0 2 87 ) ,麦克隆值与衣分存在较大的正向偏相关 (r偏=0 2 0 3) ;因此 ,在以高强纤维为目标的特用优质棉育种中 ,采用高衣分选择模式须持谨慎态度。 In this study, we analyzed the correlations of several economic traits of foreign high-fiber varieties, indicating that there is a large positive correlation between fiber strength and length (r = 0 1 81), and the micronaire value and fiber length were significantly negatively biased Therefore, it is practically feasible to select long, strong and fine fibers, but there is a significant negative correlation between fiber specific strength and lint fraction (-0.287). The micronaire value and There is a large positive correlation between the fractions (r = 0.220). Therefore, caution should be exercised when using high quality cotton selection in high-quality cotton-specific high-quality cotton breeding.
