Practical Exploration and Achievements of Maize Haploid Breeding Technology
摘要
Abstract
Double haploid breeding(DH)technology is a breeding technique that uses a parthenogenesis induction line to induce the production of parthenogenesis haploids,and then obtains homozygous diploids through natural or artificial doubling.Using this technology,it only takes 2 generations to obtain a pure line with 100%homozygosity for all traits in theory.This paper reviews the research progress on maize haploid breeding in China,focusing on haploid induction and chromosome doubling processes.It elaborates on various aspects,including the construction of basic materials,screening and improvement of induction lines,haploid induction,selection and trait identification of haploid kernels,haploid doubling,DH line propagation,phenotypic evaluation and selection,DH line combining ability testing,new hybrid combination trials,and the achievements of DH breeding applications.Furthermore,the future application prospects of maize haploid breeding technology are discussed.关键词
