Parthenocarpy, the ability to set fruits without pollination, is one of the promising agronomic traits since it has potential to achieve labor saving and cost reduction in melon cultivation. This study performed genetic analysis of parthenocarpic traits, such as fruit set ratio and fruit size, in weedy melon, in order to acquire knowledge of the inheritance for the efficient breeding. In addition, we start to breed a near isogenic line from a weedy melon accession with parthenocarpic ability by successive backcrossing with a musk melon cultivar 'Earls Favorite Harukei 3'. Genetic analysis indicated the parthenocarpic ability may be controlled by at least two recessive genes, and parthenocarpic ability is stable throughout the year. These results indicated the parthenocarpic genes of the weedy melon is useful in breeding of parthenocarpic melon cultivars.

单性结实，即不需要授粉就能坐果的能力，是甜瓜栽培中最有前途的农艺性状之一，因为它具有节省劳动力和降低成本的潜力。本研究对杂草瓜单性结实的坐果率和果实大小等性状进行了遗传分析，以期为杂草瓜的高效育种提供遗传依据。此外，我们开始培育近等基因系从杂草甜瓜加入单性结实的能力，通过连续回交与甜瓜品种'伯爵最喜爱的Harukei 3'。遗传分析表明，其单性结实性受至少两对隐性基因控制，且全年稳定。这些结果表明，杂草瓜的单性结实基因在单性结实甜瓜品种的选育中是有用的。
