本研究选用多份资料,通过对皮棉产量性状的相关与通径分析,纤维品质性状与皮棉产量的相关性分析。结果表明。为避免目前陆地棉种质普遍存在的产量与纤维品质的负相关,育种工作中除应注重种质改良与良种方法外,应从选择策略的角度,在对单位面积铃数与比强度进行选择的同时,切实加强对表指与纤维长度整齐度选择的改良目标。以利产量与品质协调增长。
In this study, a number of data were selected to analyze the correlations between the lint yield traits and the path analysis, the correlation between fiber quality traits and lint yield. The results show. In order to avoid the negative correlation between the current ubiquitous yield and the fiber quality of upland cotton germplasm, in addition to focusing on germplasm improvement and improved variety methods in breeding work, we should select the boll number and specific intensity per unit area from the perspective of selection strategy In the meantime, we must earnestly strengthen the improvement target of selecting the index and the uniformity of fiber length. To facilitate the coordinated growth of production and quality.
