单倍体的产生途径及其在作物遗传育种中的应用

Generation Ways of Haploid and Its Application in Crop Genetics and Breeding

综述了诱导单倍体产生的花药培养、远缘杂交、诱导系、着丝粒介导等途径,及其在加速育种进程、构建DH群体、非同源染色体配对研究、转基因供体、突变体研究及基因组测序中的作用。

In this paper,the haploid generation ways and its potential application in plant genetics and breeding are reviewed.Haploid can be gained by different ways,such as anther culture,distant hybridization,inducer line,centromere mediation and so on.Haploid has important actions in accelerating breeding process,building DH population,studies on non-homologous chromosome pairing,transgenic donors and mutants,and genome sequencing.
