Breeding method for no female flowers or few female flowers of a cucumber plant with less than 8 nodes

Abstract

The invention discloses a method for breeding cucumber plants with no female flowers or few female flowers below 8 nodes, comprising the following steps: cultivating female parents with no females at the lower nodes and all female parents at the middle and upper parts: hybridizing all female cucumbers with Tangshan autumn melon, Tangshan autumn melon is used as the recurrent parent of backcrossing, and 6 generations of saturated backcrossing and 6 generations of selfing are carried out, and the seeds of plants with no females in the lower nodes and all females in the middle and upper parts of the plants are selected; The cucumber of the female variety is crossed with Tangshan autumn melon, and Tangshan autumn melon is used as the recurrent parent of backcrossing, and 6 generations of backcrossing are carried out, and after 6 generations of self-crossing, the seeds of strong female plants with more than 8 nodes are selected; Anogynous, middle and upper all-feminine plant seeds are used as the female parent, and strong female plant seeds are used as the male parent, and hybridization is performed to obtain cucumber varieties with low nodes (1-8 nodes) without females or few females, high-yielding cucumber varieties, low nodes The lack of female or few female flowers solves the time-consuming and labor-intensive problems of removing the bottom female and consuming unnecessary nutrients for the plant in order to obtain high yield in production.

Description

technical field [0001] The invention relates to the technical field of vegetable breeding, in particular to a breeding method for cucumber plants with no female flowers or few female flowers below 8 nodes. Background technique [0002] The female line of cucumber is similar to the male sterile line of other plants. It is a genetically stable variety or line composed of plants that only bear female flowers but no male flowers. They must rely on external normal pollen pollination or artificial self-induction to produce fruit . Female lines play an important role in cucumber breeding and cultivation, and are now widely used in production. However, the female plants begin to grow female flowers at the seedling stage (1-8 nodes), because the nutrients produced by the young leaves of the plants at this time cannot meet the nutrients required for the swelling of young melons, and the melons produced have no commercial value; Leaving melons for a long time will cause a waste of nu...

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a method for breeding cucumbers with no female flowers or few female flowers below 8 nodes. The low node position without female flowers or few female flowers solves the time-consuming and labor-intensive problem of removing the bottom female flowers in order to obtain high yield in production. The problem of plants consuming unnecessary nutrients
