Problems solved by technology

[0002] Melons are generally of the andromonoecious plant type. When producing hybrids, emasculation and pollination are necessary. The cost of seed production is high, and the purity is difficult to guarantee. Therefore, in the production of melons in my country, most of the thin-skinned melons are normal varieties, while the high-end consumption of thick-skinned melons Most of them are hybrids, but the price of seeds is extremely high, which seriously affects the development of the melon industry
In addition to using artificial emasculation to produce hybrids, individual researchers are studying the technology of using unisexual flower varieties (dioecious plant type) as female parents to produce hybrid seeds, so as to save the operation of removing the stamens of each complete flower, so that Reduce the production cost of hybrids and improve the purity of hybrids. Although this method is improved compared with the common andromonogeneous plant type seed production, this method still needs to detassell the female parent. and the problem of incompletely producing false hybrids, this method has not yet been applied in the production of hybrid seeds

Abstract

The present invention relates to a method of producing muskmelon hybrid, and features that muskmelon hybrid is produced through hybridization of female line muskmelon variety as female parent and male full-homophyletic type muskmelon variety as male parent. Using female line muskmelon variety in producing muskmelon hybrid can omit artificial castration, artificial pollination and other operation, lower cost by 80 % and raise hybrid purity to 100 %.
