棉花早熟性常常是育种的重要目标。在棉花育种过程中,对一些入选材料如何评价其早熟或是早衰,多年来在认识上有争议。在实际工作中,往往注意了早衰却出现了晚熟;注意了早熟性又常带来早衰。因此在棉花育种工作中,对早熟与早衰确立一个正确的概念和区分标准,将有利于指导育种实践,并进而可选育出真正的既早熟又不早衰的棉花新品种。
Cotton precocity is often an important breeding goal. During the cotton breeding process, it is controversial over the years for some selected materials to evaluate their precocious or premature aging. In actual work, often pay attention to premature aging but appeared late maturity; attention to premature and often bring about premature aging. Therefore, establishing a correct concept and distinguishing criteria for precocious and premature aging in cotton breeding will be conducive to guiding breeding practice and, in turn, breeding new real cotton varieties that are neither premature nor premature.
