棉花早熟性研究进展及其应用

早熟棉适于麦(油)后直播,实现粮棉一年两熟,对棉花产业稳定发展具有重要意义。本文对早熟性的遗传特性、早熟相关QTL定位、早熟相关基因挖掘的进展进行了阐述;总结了早熟棉的发展与育种现状以及早熟棉种质资源的创新利用;介绍了早熟棉在我国黄河流域、长江流域、西北内陆棉区的生产示范应用情况;提出了我国早熟棉育种的研究展望,为我国早熟棉育种提供参考。

Research Progress and Application of Early Maturity in Upland Cotton

Early-maturity cotton is suitable for direct-seeded after wheat (rape) harvest and realize the crop system of grain and cotton two crops a year.Early-maturity cotton is of great significance to the stable development of cotton industry.This paper showed the research progress of genetic characteristics of early maturity,QTL mapping of earliness-related traits and mining of earliness-related gene.We summarized the breeding development and the creation and application of germplasm resources in early-maturity cotton.The demonstration and application of early-maturity cotton in Yellow River basin,Yangtze River basin and northwest inland of China were showed.The prospect of breeding was brought in early-maturity cotton.This report will provide reference for early-maturity cotton breeding in China.
