棉花杂种优势利用是提高产量的有效途径。亲本选择和组合配制恰当与否将直接影响优势的大小及杂交棉的利用和推广。为了减少选择亲本和配制组合的盲目性,找出一些预测杂种优势的指标和依据是十分重要的。杂种优势是生物界普遍存在的复杂现象,它牵涉到基因之间,核质之间,细胞内 The utilization of cotton heterosis is an effective way to increase yield. Proper selection of parents and combinations will directly affect the size of advantages and utilization and promotion of hybrid cotton. In order to reduce the blindness of selection of parents and combinations, it is important to find some indicators and basis for the prediction of heterosis. Heterosis is a common complex phenomenon in the biological world, which involves genes, between nuclear, intracellular
