Abstract: 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.
