Embodiment Construction

[0031] The breeding method of all-female processed cucumber Youjia Quanfe 09, including:

[0032] 1. The source and traits of the parents: (References for the description of the following traits: Li Xixiang, Zhu Dewei, etc. Specifications and data standards for cucumber germplasm resources description [M]. Beijing: China Agricultural Press, 2005.8-34)

[0033] 1) Whole female cucumber

[0034] The stable female line 410, which was bred by 7 generations of selfing from the American commercial cucumber Marketmore 97 (commercially available), is an American sliced ​​cucumber. It is an all-female high-generation inbred line homozygous for the female gene. Medium-sized, the main vine is 2-2.5 meters long; the leaves are dark green, palm-shaped and pentagonal, the leaves are shallow, the tip of the leaves is pointed, and the number of leaf hairs is medium. 19.0 cm, melon thorns are sparse in number, and the color of melon thorns is white.

[0035] 2) Monoecious cucumbers

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 bebackcrossed 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 obtainingthe 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...
