棉花矮化机理研究进展

棉花矮化植株具有强抗倒伏和高产的特点,对棉花育种具有重要作用。近年来,棉花矮化性状的研究集中在突变体的收集、创造及表型和遗传特点、矮化性状与激素的关系上,矮化基因的发掘研究与利用也越来越受到重视。综述了棉花矮化育种的意义,矮化性状与激素的关系,对国内外激素相关的棉花矮化性状的机理的最新研究进展作了详细地总结,并探讨了棉花矮化分子机理的研究进展,提出棉花矮化育种存在的问题及发展方向。

Research Progress on Dwarfing Mechanism of Cotton

The dwarf character of cotton displays a good resistance to lodging and usually gets high yield , which plays an important role in cotton breeding.In recent years , the research on dwarf cotton focus on the collection , creation , phenotypic and genetic characteristics of mutant , the relationship between dwarfing traits and hormone , and more and more attention has been paid on the exploitation and utilization of dwarfing gene. The significance of cotton dwarfing breeding , the relationship between dwarfing traits and hormone were summarized. It's concluded that the latest research progress in molecular mechanism on cotton hormone related dwarfing traits at home and abroad in details , and the dwarfing molecular mechanism of cotton were discussed. The problems of cotton dwarfing breeding were analyzed , and development direction was prospected.
