Loofah net house seed production method

Abstract

The invention discloses a loofah net house seed production method. A female and male parent cropping pattern is set in a net house to achieve zoned relay intercropping of female parent seeds and male parent seeds on a biconcave-structure cultivation ridge, and the male parent seeds do not additionally occupy land, so that the purposes of increasing the number of female parent plants in the total area of a seed production land parcel and improving the growth environment of female and male parent plants are fulfilled, and the yield and the quality of hybrid seeds of a loofah can be improved. The yield of the hybrid seeds of the loofah is improved by 29.1-31.3%, and the thousand seed weight is increased by 7.0-7.2g.

Description

technical field [0001] The invention relates to a luffa seed production method, which belongs to the technical field of vegetable breeding. Background technique [0002] Luffa hybrid seed production is aimed at producing high-quality hybrid seeds, using the dominance of the male and female parents of the loofah to produce seeds that are significantly superior to their parents in terms of high yield, disease resistance, and stress resistance through artificial hybrid seed production. Hybrid breed. In the process of hybrid seed production of loofah, there are problems such as low yield, difficulty in effective control of seed quality and purity, and high production cost. These problems restrict the development of loofah seed industry to a certain extent. [0003] The technical defects of traditional conventional hybrid seed production of loofah are mainly manifested in: [0004] (1) The male parent and the female parent of the loofah are usually planted separately and intens...

AI Technical Summary

Problems solved by technology

[0004] (1) The male parent and female parent of the loofah are usually planted in separate partitions, 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 parental hybrids are not completely removed, resulting in the generation of false hybrids and the decrease in the purity of hybrid seeds

[0007] (4) Long-distance isolation areas must be set up, and multiple loofah hybrids cannot be propagated at close distances in the same base, and the breeding cost will increase
