Embodiment Construction

[0012] The soybean hybrid seed production method comprises the selection of soybean male sterile female parent and restorer male parent, and the sowing of male parent and female parent, and interplanting broad beans at a ratio of 9:1 while sowing male and female soybean parents, That is to sow 9 rows of soybeans and 1 row of broad beans; the male parent and the female parent are sown at a ratio of 1:2, that is, one row of male parents and two rows of female parents are sown. At the same time, the soybean row spacing is 2.0 feet and the plant spacing is 4 inches. .

[0013] The 40-meter range around the soybean farming field is set as an isolated area, and it is forbidden to sow soybean seeds or sow seeds of other crops that have a very distant biological relationship with soybeans in this isolated area.

[0014] During the flowering period of soybeans, especially in the middle and late stages of the flowering period, it is best to beat the bean plants with bamboo poles at 11:3...

Abstract

The soybean hybrid seed producing method includes selection of male sterile line as female parent and restorer line as male parent and seeding of both male and female parents while interplanting broad bean. Broad bean is used as common thrips attracting crop and it can promote the propagation of common thrips, raise insect population density in the seed producing field and raise the heterogenic hybridization rate. By means of the technological measures of natural attraction of insect, artificial field pollination, pollinating insect protection, etc., the soybean hybrid seed producing method has high efficiency and low cost, and produce soybean hybrid seed suitable for large-area and large-scale application in various area.

Description

technical field [0001] The invention relates to the seed production technology of crop hybrids, in particular to a soybean hybrid seed production method. Background technique [0002] The cultivation of soybean male sterile lines, maintainer lines, and restorer lines is a mature existing known technology. For example, existing soybean male sterile lines include photosensitive male sterile lines, cytoplasmic male sterile lines, nuclear male sterile lines, and nuclear male sterile lines. Breeding lines, etc., but because some key technical problems have not been well resolved, the prior art does not have a set of mature and practical soybean hybrid seed production technology at present. [0003] Soybean is a strictly self-pollinating crop, and its outcrossing rate usually does not exceed 3‰. In addition to other seed production-related issues such as the selection of male and female parents in hybrid seed production, the pollinator of pollen is a key issue that needs to be so...
