Method for producing seeds of rootstock-used pumpkins in solar greenhouse

Abstract

The invention discloses a method for producing seeds of rootstock-used pumpkin in a solar greenhouse. A female parent and male parent planting mode is set and improved in the solar greenhouse, banding relay cropping planting of male parents and female parents on a cultivation ridge with a double-concave structure is realized, male parents do not occupy extra land, the purposes of increasing the planting number of the female parents on the total area of a seed production land parcel and improving a growing environment of male parent and female parent plants are achieved, and yield and quality of the hybrid seeds of the rootstock-used pumpkins are improved. The yield of the hybrid seeds of the rootstock-used pumpkins is improved by 25.4%-28.7%, and the thousand seed weight is increased by 11.2-11.4 g.

Description

technical field [0001] The invention relates to a seed production method of pumpkins for anvils in a solar greenhouse, belonging to the technical field of vegetable breeding. Background technique [0002] The hybrid seed production of rootstock pumpkin is aimed at the production of high-quality hybrid seeds, using the superiority of the male parent and the female parent, through artificial hybrid seed production, to produce seeds that are significantly superior to their parents in terms of high yield, disease resistance, and stress resistance. of hybrid varieties. In the process of hybrid seed production of pumpkin, there are problems such as low yield, difficulty in effectively controlling seed quality and purity, and high production costs. These problems restrict the development of pumpkin seed industry to a certain extent. [0003] The technical defects of traditional conventional hybrid seed production of rootstock pumpkin are mainly manifested in: [0004] (1) The mal...

AI Technical Summary

Problems solved by technology

[0004] (1) The male parent and the female parent of pumpkins for rootstock are usually planted separately and intensively, and the male parent occupies an independent land area, which reduces the number of planting plants of the female parent on the total area of ​​the seed production plot, resulting in low yield of hybrid seeds

[0005] (2) In order to reduce the area occupied by the male parent, the method of increasing the planting density is usually used to plant the male parent, resulting in disorderly competition among the male plants, so that the male flowers of the plant cannot get better nutritional conditions, and the male flowers are poorly developed. Decreased pollen quantity is not conducive to pollination, resulting in poor quality of hybrid pollination

[0006] (3) The timing and method of removing hybrids are unscientific, and the removal of parental hybrids is not thorough, resulting in the generation of false hybrids and a decrease in the purity of hybrid seeds

[0007] (4) A long-distance isolation area must be set up, and multiple rootstock pumpkin hybrids cannot be propagated in the same base at close distances, and the breeding cost will increase
