在甜瓜（Cucumis meloL.）中，在冬季和早春的低温下，可育花粉的数量减少，从而限制了受精。克服这一问题的一个有希望的方法是开发单性结实的品种。单性结实的黄瓜和南瓜，但不是甜瓜品种。在这项研究中，我们探讨了172加入从东亚甜瓜收集和鉴定加入表现出强单性结实能力，全年。单性结实的加入和非单性结实品种之间的杂交，以及单性结实的加入之间的杂交表明，单性结实可能以隐性方式遗传，并且可能由这些加入中的相同基因或基因控制。单性结实指标，如单性结实果实的大小和数量，不同的栽培时期，表明单性结实果实发育的环境因素的重要性。我们认为，利用鉴定的种质资源选育出具有全年稳定单性结实能力的新品种是可能的。
In melon (Cucumis meloL.), the amount of fertile pollen decreases at low temperature during winter and early spring and thereby restricts fertilization. A promising way to overcome this problem is to develop parthenocarpic cultivars. Parthenocarpic cucumber and squash, but not melon cultivars are available. In this study, we explored 172 accessions from an East Asian melon collection and identified accessions that exhibited strong parthenocarpic ability throughout the year. Crosses between parthenocarpic accessions and a non-parthenocarpic cultivar, and among parthenocarpic accessions indicated that parthenocarpy may be inherited in a recessive manner and is likely controlled by the same gene or genes in these accessions. The parthenocarpic indices, such as the size and number of parthenocarpic fruits, differed among the cultivation periods, indicating the importance of environmental factors for parthenocarpic fruit development. We conclude that it is possible to breed new cultivars with stable parthenocarpic ability throughout the year by using the identified accessions.
