Culture and application of No.3 North China hologynic cucumber of hologynic North China type cucumbers

Abstract

The invention relates to culture and application of a No.3 North China hologynic cucumber of hologynic North China type cucumbers, which belong to the field of biotechnology breeding. The culture comprises the following steps of: hybridizing monoecious North China type cucumbers CC3 with hologynic European greenhouse type cucumbers EC1 to obtain F1, and performing backcross between the F1 and theCC3; selecting hologynic single plants from backcross offspring to perform continuous backcross with monoecious cucumber parents CC3 for 7 generations; selecting hologynic single plants of BC7F1 to perform selfing; selecting hologynic single plants of BC7F2 to perform selfing continuously; and finally, selecting a strain of hologynic single plants of BC7F3, and performing mixed pollination on thecucumbers of the strain to obtain a new variety of the hologynic North China type cucumbers, namely the No.3 North China hologynic cucumber which has strong growth potential, high quality and high yield. A hologynic cucumber variety with high feed purity and strong heterosis can be obtained by hybridizing the No.3 North China hologynic cucumber with a commonly-cultured cucumber.

Description

1. Technical field [0001] The cultivation and application of the all-female Huabei type cucumber No. Huabei Quane No. 3 of the invention belongs to the field of biotechnology breeding, and is specially used for cultivating new all-female type cucumber varieties. 2. Background technology [0002] Cucumber is one of the main vegetable crops widely cultivated in the world, and its cultivation area ranks first among the vegetables in protected areas in my country, which plays a very important role in ensuring the balanced annual supply of vegetables in my country. [0003] Cucumbers are dioecious annual plants. Flower buds occur at the seedling stage, and the sex type differentiation of flower buds is carried out. Flowers are generally unisexual, but some have complete flowers in addition to female flowers and male flowers. Its plant sex types are: pure female plant, monoecious plant, pure male plant, pure whole plant, androgynous plant, and monoecious plant. Among them, pure...

Problems solved by technology

However, at present, the all-female varieties of domestic cucumbers are mainly European greenhouse cucumbers imported from abroad, and the ecological type is relatively single, which cannot meet the needs of production and breeding.
