Background
Melon (Cucumis melo.l) is an annual vining herb of the genus cucurbitaceae, and is one of the important cash crops of cucurbitaceae. The phenomenon of seed dormancy refers to the phenomenon that the plant does not germinate or grows very slowly or temporarily stops under a proper growth environment, and is an active adaptation process of the plant to resist and adapt to a poor environment. The phenomenon of seed after-ripening is common in plants, that is, the dormancy of seeds can be broken after the seeds are dried for a period of time, but the regulation and control mechanisms in different plants are different. The dormancy of the melon seeds has great significance for large-scale production, not only affects the uniformity of germination, but also has different degrees of influence on the cultivation of strong seedlings, the yield and the quality. Through researching the dormancy traits of melon seeds, not only can the varieties with dormancy genes potentially exist be planned and planted and separately managed, thereby achieving the purposes of saving management cost and balanced supply in the market, but also the molecular markers can be used for screening the varieties with dormancy/non-dormancy of the seeds, so that the economic benefit brought to producers by early marketing of the melon is improved, and therefore, the dormancy trait genes of the melon seeds are positioned by constructing a genetic linkage map, the molecular markers with linked dormancy traits are obtained, theoretical basis is provided for auxiliary selection and breeding of the melon molecular markers, and foundation is provided for excavation and functional analysis of related genes of dormancy of the melon seeds.
