随着我国棉花产量的提高转向纤维品质的改进,由原棉国内市场的销售转向国外市场的开拓,我国现有棉花品种的纤维品质越来越不适应纺纱工业的要求。因此,棉花纤维品质育种已列为国家攻关课题;有关纤维品质遗传的研究已引起广大育种工作者的高度重视。为了探讨棉花纤维品质与纺纱质量的相关关系,近年来,我们对全国各育种单位最近培育的34个棉花新品种的纤维品质进行了相关系数的估测,并对这些纤维物理性
With the improvement of cotton production in our country, the improvement of fiber quality has shifted from the sale of raw cotton in the domestic market to the overseas market. The fiber quality of the existing cotton varieties in our country is becoming more and more unsuited to the requirements of the spinning industry. Therefore, the quality of cotton fiber breeding has been listed as a national research topic; genetic fiber quality research has attracted the majority of breeding workers attach great importance. In order to explore the relationship between the quality of cotton fiber and the quality of cotton spinning, in recent years, we estimated the fiber quality of 34 new cotton varieties cultivated by various breeding units in China and compared their physical properties
