摘要
单株皮棉产量主要通过衣分和单株结铃性来实现，铃重与纤维长度呈显著的正相关，纤维细度与产量，纤维强度均呈现出较高的负相关。今后育种应注意产量、纤维强度与细度的同步提高。
Using polybasic statistics analysis method,the corrlative hereditary was studied between main output charaters and guality charaeters for the upland cottan. The result showed that ginned cottan output perplant was produced through lint and ball foriming per plant.Significant positive correlation exited between per ball weight and fibre length. Between fine degree and yield and intensity has higaher negtive correlation. That the cotton cultivars were lower in fine degree and more attention shouldbe baid in the synchronous improvment of output and fine degree in the future breeding.
