植物单倍体诱导技术研究进展
Research Progress on Haploid Induction Technology in Plant
摘要
Abstract
With the advancement of breeding technologies and the genetic improvement of crop varieties,crop yields have greatly increased,helping to address the growing food demand.However,conventional breeding cycles are too long,typically requiring 6 to 8 years to obtain homozygous inbred lines,which severely limits the rate of new variety development.Double haploid(DH)technology,an important breeding technique in recent years,can significantly shorten the breeding cycle and improve breeding efficiency.Although significant progress has been made in areas such as haploid induction gene discovery,haploid induction system establishment,haploid screening method optimization,and chromosome doubling technology improvement,the efficiency of haploid induction(HI)has not yet met production expectations.Furthermore,the genetic knowledge system remains incomplete,and haploid identification systems differ across species.Therefore,the exploration of new genes for haploid induction and the creation of highly efficient haploid induction lines and haploid identification system are key methods for addressing the application bottleneck of double haploid technology.In this article,the significance of research on double haploid induction technology,the current status of haploid induction gene research,the causes of haploid induction,and research progress on haploid identification methods were reviewed.it provided reference for exploration of new genes for haploid induction in plants,aggregated creation of highly efficient haploid induction lines and haploid identification lines,and analysis of the genetic basis of haploid induction.Additionally,It offered theoretical and technical support for the establishment of crop haploid induction systems and their application in crop breeding.关键词
