摘　　要：单倍体和双单倍体对于作物改良和遗传分析具有重要意义。在瓜类作物的研究中,通过诱导离体雌核发育是获得单倍体和双单倍体的有效途径。综述了瓜类作物未受精子房和胚珠离体培养的研究概况及影响因素,总结了再生植株鉴定、单倍体加倍和应用方面的进展,分析了目前研究存在的问题以及未来的研究方向,最后对瓜类作物单倍体研究的发展前景做简要地展望,以期为后续瓜类作物离体雌核发育诱导单倍体的研究提供参考。Haploid and double haploid are of great significance for crop improvement and genetic analysis.In the study of cucurbits crops,in vitro gynogenesis is an effective way to obtain haploid and double haploid.Here we mainly review the research overview and major factors of the in vitro unfertilized ovule and ovary culture in cucurbit crops and summarize the progress in the identification of regenerated plants,haploid doubling,and related application.Besides,the existing problems and further research directions are also analyzed.Finally,the prospects for the development of haploid research in cucurbits crops are briefly prospected.This provides a reference for the following studies on the inducing haploid development of in vitro gynogenesis in cucurbits crops.
