西瓜甜瓜育种中的染色体倍性操作及倍性鉴定

Manipulation and Identification of Chromosomal Ploidy in Watermelon and Muskmelon Breeding

系统地介绍了西瓜和甜瓜育种中的单倍体及多倍体(三倍体和四倍体)水平的倍性操作技术。对单倍体植株的诱导及双单倍体的产生、植株整体水平和离体水平上诱导四倍体变异、三倍体育种及不同倍性水平的鉴定等研究方法和进展作了详细的评述。

The advances on chromosomal manipulation for producing hap loid and polyploid(triploid and tetraploid)in water-melon(Citrullus lanatus)and muskmelon(Cucumis melo)breeding has been re viewed in this paper.Tech niques in volved in induction of haploid plant and chromo some dou bling in haploid,regeneration of tetraploid plant in duced in vitro and in vivo,triploid breeding and identification of the different ploidy levels in watermelon and muskmelon are dis cussed.
