高产优质是棉花育种的主要目标之一。由于基因的一因多效或连锁遗传，棉花的产量和纤维品质性状间多存在着高度的负相关。对此，棉花育种者曾进行了长期的探索。近年，选育出的一批棉花新品种，一定程度上兼顾了产量与品质的关系。为探讨新的育种策略，我们于１９９６～１９９ High-yielding and high-quality cotton breeding is one of the main objectives. Due to the multi-effect of genes and their inheritance, there is a high degree of negative correlation between cotton yield and fiber quality traits. In response, cotton breeders have conducted long-term exploration. In recent years, a new crop of cotton bred new varieties, to some extent take into account the relationship between yield and quality. To explore a new breeding strategy, we in 1996 ~ 199
