Embodiment

[0022] like figure 1 Shown, the breeding process of the present embodiment is as follows:

[0023] Female parent selection:

[0024] 1. In the spring of 2004, the Chinese pumpkin "Wuman No. 4" with good disease resistance (available from Shanghai Yihan Seedling Trading Co., Ltd.) was used as the female parent, and the Western squash with better quality "Jinli" was used as the female parent. "(Shanghai Yihan Seedling Trading Co., Ltd. for sale) is used as the male parent to cross to obtain hybrid seeds F1.

[0025] 2. In the spring of 2005, the hybrid seed F1 was sown and cultivated. Among the offspring, a single plant with excellent comprehensive traits was selected according to the breeding goals of no vines, high quality, disease resistance, and high yield.

[0026] 3. In the spring of the second year, self-seeds are sown and cultivated, and self-bred seedlings with excellent comprehensive traits are selected from the offspring according to the breeding goals of no vines, ...

Abstract

The invention relates to a pumpkin breeding method, in particular relates to a cucurbita maxima breeding method, and belongs to the technical field of plant breeding. At present, all of cucurbita maxima have stems; as the stemless cucurbita maxima is dominant for the stemmed cucurbita maxima, all of the first filial generations after the stemless cucurbita maxima is hybridized with the stemmed cucurbita maxima do not have the stems. According to the method, the stemless cucurbita maxima is bred; Chinese pumpkins with high temperature resistance and good disease resistance are utilized as materials; the stemless cucurbita maxima bred through different interspecific hybridization solves the problems that existing cucurbita maxima is not resistant to high temperature and can be easily infected with virus diseases; a new stemless cucurbita maxima variety with good quality and good disease resistance is bred.

Description

technical field [0001] The invention relates to a pumpkin breeding method, in particular to a pumpkin breeding method, and belongs to the technical field of plant breeding. Background technique [0002] Western squash (that is, Indian pumpkin), also known as chestnut squash, is one of the three main cultivars of the genus Cucurbita. The quality of Western squash is excellent, and the content of various nutrients has increased to varying degrees compared with Chinese pumpkin, and the appearance is beautiful. , Exquisite, popular in China soon. Because watermelon squash is generally not resistant to high temperatures, viral diseases are very serious in hot summer, and late sowing in spring or cultivation in autumn often results in failure of harvest, which has great limitations in the scope of application. At present, pumpkins are all vines, and the cultivation not only requires vine pressing and erecting, which is labor-intensive, but also occupies a lot of land, and the num...
