摘要:
棉花是重要的经济作物,是天然纺织纤维的主要来源。我国是棉花生产大国和消费大国,但随着近年来温室效应加剧,频繁且持续发生的高温天气严重制约了我国的棉花生产。因此,棉花科技工作者开始关注棉花响应高温胁迫的研究,以期培育耐高温棉花品种以减少损失。本文对棉花响应高温胁迫的机制及耐高温种质创新研究进行综述,主要内容包括:(1)棉花受高温胁迫的表型特征及评价方法;(2)棉花响应高温的遗传及生理生化机理;(3)棉花耐高温种质创新及应用,意在为棉花耐高温机制解析、种质创新和育种、棉花生产等提供参考信息。

Abstract:
Cotton is a pivotal industrial crop, mainly cultivated for producing natural textile fibers. Considering its versatile capacity, cotton industry occupies indispensable strategic position at the national level. With the intensified greenhouse effect, the frequent and continuously occurring high temperature weather severely limited the cotton production in China and in the world. In the last decade, research groups have made visible progress in investigating the response of cotton to high temperature stress in order to breed high temperature tolerant cultivars to reduce yield loss. This review summaries the advances mainly including: (1) effective evaluation systems of high temperature tolerance performance in cotton; (2) genetic, physiological and biochemical mechanisms of high temperature tolerance in cotton; (3) high temperature tolerant germplasm innovation of cotton and breeding practice. We expect to raise questions and suggestions for cotton high temperature tolerance research, germplasm innovation and breeding practice in future.
Key words:  cotton  high temperature response  phenotype evaluation  mechanism exploration  germplasm resources innovation
