Research Progress and Prospects of Doubled Haploid Technology in Rice
摘要
Abstract
Doubled haploid(DH)technology accelerates the production of fully homozygous breeding lines within just 1 to 2 generations,representing a significant improvement over conventional methods that require 6 to 10 generations of selfing or backcrossing.The process involves four key steps:haploid induction,haploid identification,chromosome doubling,and the cultivation and application of doubled haploids(DHs).Haploid induction,which serves as the foundation of this system,currently employs two main approaches in rice:(1)the well-established anther culture method and(2)the emerging hybridization-based method utilizing haploid inducers(HIs).This review highlights recent advances in HI-mediated DH technology for rice,analyzes the technical challenges encountered at each step,and explores its future applications in rice breeding.关键词
