摘要:
黄瓜属有约70 余种植物,含有丰富的野生资源,广泛分布于非洲、亚洲、澳洲的75 个国家。栽培黄瓜遗传基础 狭窄,而黄瓜近源野生资源中含有诸多栽培黄瓜所迫切需要的优异基因,是栽培黄瓜遗传改良的丰富基因源和物质基础。本 文介绍了黄瓜属植物的分布与分类、黄瓜主要近源野生植物的起源与发现、优良种间遗传资源的创制,着重阐述了近年来黄 瓜主要近源野生资源的研究进展,最后提出了目前在野生资源利用方面存在的问题,并对未来利用野生资源改良和创制黄瓜 新品种提出了展望。本文对葫芦科作物基因发掘与遗传改良具有重要的借鉴和指导意义。

Abstract:
The genus Cucumis includes about 70 species to date, and plants from this genus are found in 75 countries of Africa, Asia and Australia. The cultivated cucumber , which is important in daily diet, represented a narrow genetic diversity. The exploration and incorporation of elite and diversified genes, which were derived from wild relatives, are of great interest, in order to enrich the genetic basis of cultivated cucumber and the practical uses in breeding for new varieties. This review introduces the distribution and classification of Cucumis plants, the origin and discovery of the main wild relatives, the innovation of genetic resources between species, and finally emphasizes the research progress of the main wild species. Based on the expertise, the problems in the utilization of wild resources are summarized and the actions to improve and create novel cucumber varieties by incorporating wild resources are proposed. This work thus provides reference and guidance for the gene mining and genetic improvement of Cucurbits.
Key words:  Cucumis genus  wild species  genetic improvement
