Example Embodiment

[0031] The breeding method of all-female processed cucumber Youjia All-female 09 includes:

[0032] 1. The source and traits of the parents: (reference for the description of the following traits: Li Xixiang, Zhu Dewei, etc. Cucumber germplasm resource description specifications and data standards [M]. Beijing: China Agriculture Press, 2005.8-34)

[0033] 1) Full female cucumber

[0034] The stable female line 410, bred from the American commercial cucumber Marketmore 97 (commercially available) through 7 generations of self-breeding, is an American sliced ​​cucumber. It is an all-female high-generation inbred line that is homozygous for the female gene. Medium, the main vine is 2-2.5 meters long; the leaves are dark green with palm-shaped pentagons, leaf splits are shallow, the tip shape is pointed, the number of leaf hairs is medium, the commercial melon is dark green, the melon strips are rod-shaped, and the length is 18.5- 19.0 cm, the number of thorns is sparse, and the color o...

Abstract

The invention relates to cultivation and an application of a full female processing cucumber Youjia full female 09 and belongs to the field of biotechnology breeding. A full female American slicing cucumber 410 is hybridized with a monoecious type processing cucumber HH1-8-1-2, the obtained F1 is backcrossed with HH1-8-1-2, a full-female single plant is selected in the backcross generations to be backcrossed with the monoecious type cucumber parent HH1-8-1-2 for 4 generations continuously, the full-female single plant of BC4F1 is selected to be self-crossed, the full-female single plant is selected in BC4F2 to be self-crossed, finally, a plant system the BC4F3 of which are all full female plants is selected, and mixed pollination is carried out on the cucumber plant system, thus obtaining the new-type full female processing cucumber Youjia full female 09, which has strong growth potential, good quality and high yield. The Youjia full female 09 can be hybridized with an ordinary cultivating cucumber to obtain a full-female cucumber variety which has high seed purity and strong heterosis.

Description

1. Technical field [0001] The cultivation and application of the all-female processed cucumber Youjia Quane 09 of the invention belongs to the field of biotechnology breeding, and is specially used for cultivating new all-female 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 female plants...
