The paper summarizes studies of in vitro inducement of haploids in cucurbitaceae, including anther culture, in vitro gynogenesis culture and induction of haploid obtained by irradiated pollen. The factors affectting in vitro inducement such as material genetype, medium, pretreatment, megaspores development stage and others had significant effects on the embryoids inductivities.

At present, regeneration system of cotyledons, hypocotyls, and stems, protoplasts and cotyledons codes have been established among Cucurbitaceae. There are several methods of transformation, such as agrobacteria -medidated genetic, particle gun, pollen tube passage, DNA soaking, ovary embryonary sac injection. Transgenic is tending to antivirotic and delayed maturity. Selection marker used often is NPT II.

目前，在葫芦科植物中已建立了子叶、茎尖、胚轴、茎段、原生质体和子叶节等的再生体系；用于遗传转化的方法有农杆菌介导法、基因枪法、花粉管通道法、DNA浸泡法等；用于转化的目的基因多为抗病毒病基因和延迟成熟的基因；NPTII基因为最常用的筛选标记基因。
