Problems solved by technology

[0002] At present, the main zucchini varieties in the market have short melon strips, and the melons turn white in the later stage. The most important thing is that in the process of planting in the open field in the south, the anti-virus ability is poor, and only about 7-10 melons can be harvested and there are many flower melons, which is serious. Some even failed to harvest, and the plants basically could no longer set fruit, which caused great losses to the growers.

Embodiment Construction

[0010] A method for selecting and breeding disease-resistant zucchini, which adopts the following steps:

[0011] 1. First, the female parent is the HS96-152 zucchini variety, which is dark green in color, has ribs, and has long strips, but the disease resistance is slightly poor, and the color of the peel is too dark. The male parent is the GS99-113 zucchini variety, which is highly resistant to viruses , the color is green, the length of the melon is moderate, but the color of the melon becomes lighter in the later stage;

[0012] 2. Crossbreed HS96-152 as the female parent and GS99-113 as the male parent to obtain the first generation of hybrid HDS13-09. The first generation of hybrid HDS13-09 was planted and separated for 8 generations in multiple places and at multiple points, and selected from them to meet the requirements of Guatiao. It is required to elongate first and then grow thicker, the color is lighter than the female parent, and the disease resistance is outstan...

Abstract

The invention discloses a breeding method for disease-resistant summer squashes, and relates to the technical field of crossbreeding. Conventional homemade dark-green summer squashes HS96-152 used as a female parent and high-disease-resistance summer squashes GS99-113 used as a male parent are hybridized to obtain a first-filial generation; the first-filial generation is subjected to 6-8 generation separation, purification and rejuvenation to breed summer squashes with strips which extend first and then grow stronger. According to the summer squashes, the post-stage summer squashes cannot be shortened and are green and outstanding in disease resistance.

Description

technical field [0001] The invention relates to the technical field of hybrid breeding, in particular to a method for breeding disease-resistant zucchini. Background technique [0002] At present, the main zucchini varieties in the market have short melon strips, and the melons turn white in the later stage. The most important thing is that in the process of planting in the open field in the south, the anti-virus ability is poor, and only about 7-10 melons can be harvested and there are many flower melons, which is serious. Some even failed to harvest, and the plants basically could no longer set fruit, which caused great losses to the growers. Contents of the invention [0003] The object of the present invention is to provide a method for breeding disease-resistant zucchini. The zucchini bred by the method can ensure that the zucchini in the later stage will not be shortened, and at the same time, the color is green and the disease resistance is outstanding. [0004] In...
