摘要
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。
Using multiple data the correlation and path coefficent analysis on lint yield and the correlation of important fiber quality with lint yield showed that for breaking the negative correlation between the lint yield and fiber quality cotton breeding should be focused on seletive strategies besides germplasm improvement and breeding methods.lint index and length uniformity should be used as the improvement goals while attentions be pald also on boll numbers/m^2 and fiber strength in order to increase the lint yield and fiber quality coordinately.
