辐射诱变在巴基斯坦改良棉花品种资源和育种中的应用

摘要

作者介绍了利用近三十年来,巴基斯坦在利用辐射诱变产生变异来进行棉花遗传资源改良和新品种选育中的方法、特点和取得的成就,自上世纪九十年代以来由于棉花卷叶病毒病的发生和流行对棉花科研带来的挑战与机遇,并对未来辐射诱变作为遗传资源改良和品种选育的方法的发展方向作了概述.%The authors introduced the methods, characteristics and achievements of induced mutagenesis in cotton (Gossypium Hirsutum L. )germplasm improvement and cultivar evolution in Pakistan after its independence. Since 1990s,the occurrence and prevalence of cotton leaf curl virus (CLCuV) disease brought new challenges and opportunities to cotton scientific researches.The future development of induced mutagenesis as a genetic improvement tool in cotton germplasm improvement, and cultivar evolution in Pakistan were briefly summarized.
