Problems solved by technology

Soybean is a typical self-pollination crop, which is conducive to maintaining individuals with excellent genotypes, but not conducive to gene recombination. Cross-pollination is conducive to gene recombination, but not conducive to maintaining individuals with excellent genotypes
Soybean flower organs are small, the survival rate of artificial hybridization is low, and the number of artificially configured parental hybrid combinations is limited by manpower and material resources, resulting in limited parental sources and a relatively narrow genetic basis

experiment example 1

[0079]In this experiment, the first group of exquisite soybeans produced in Example 1 in this experimental example was taken from Example 1.

[0080]Planting excellent soybeans first planting, a perpendicular is 2m, the linear spacing is 50cm, and the line spacing is 10cm; the planting is stable, the plant plant is planted, the plant plant plant is 4 lines, the line leader is 4m, the line spacing 50cm, strain 10cm, harvest soybeans.

[0081]The control of soybeans is 6, using the same implantation method as the excellent soybean selected in this experiment, and the harvest after planting.

[0082]In this experiment, the crude protein content of soybean grains was 39.23%, the thick fat content was 21.12%, and the weight of 19.31 g of the hundredweights was 334.91kg of 2016, 8.9% from the control. The yield is 388.91kg, 2017 It was 9% compared to the control; 318.5kg of 2018, 11.2% from the control. In 2019, experts have produced production, and the yield is 319.36kg.

experiment example 2

[0084]The second group of exquisite soybeans produced in Example 1 in this experimental example was selected from the group consisting of in Example 1.

[0085]Planting excellent soybeans first planting, a perpendicular is 2m, the linear spacing is 50cm, and the line spacing is 10cm; the planting is stable, the plant plant is planted, the plant plant plant is 4 lines, the line leader is 4m, the line spacing 50cm, strain 10cm, harvest soybeans.

[0086]The control of soybeans is 6, using the same implantation method as the excellent soybean selected in this experiment, and the harvest after planting.

[0087]In this experiment, the crude protein content of soybean seed grains was 39.07%, the crude fat content was 20.38%, and the 100 grain weight was 19.12 g. The yield of 2018 was 343.13 kg, which was 20% higher than the control.

Abstract

The invention relates to the technical field of crop breeding, and provides a breeding method for creating a new soybean germplasm. Natural open type natural hybridization is adopted, so that multi-gene recombination is achieved, genetic diversity is richer, complex procedures of artificial hybridization are overcome, and labor and time are saved. The method includes the steps that male parent soybeans and male genic male sterile female fertile female parent soybeans are planted, and harvesting is conducted to obtain basic soybeans and sterile plant grains; excellent soybeans are selected from the basic soybeans for planting, quality analysis is performed after harvesting, and breeding is completed; the plant height of the male parent soybeans and the plant height of the female parent soybeans are 80-90 cm independently; the grain protein is not less than 38% independently; and the grain fat content is independently greater than or equal to 18%. By hybridizing a soybean ms1 sterile plant and an excellent germplasm, the genetic basis of the soybean is separated and enriched, and the basic population is continuously optimized and improved. The provided breeding method for creating the new soybean germplasm is simple, rapid, high in selection efficiency, easy to master and convenient to operate.

Description

Technical field[0001]The present invention relates to the field of crop breeding, in particular, to a breeding method for creating soybeans.Background technique[0002]Soy originated in my country, rich in germplasm resources, contains a variety of benefits to develop and utilize. Soy is a typical self-pollinating crop, which is advantageous for maintaining an individual of an excellent genotype, which is not conducive to the recombinant of the gene, which is conducive to the recombination of the gene, which is not conducive to maintaining an individual with excellent genotype. Soybean floral organs are small, and the number of artificial hybrids is low, and the number of manual allocation of parental hybrids is affected by human and material resources, resulting in restrictions, and the genetic foundation is narrow.Inventive content[0003]It is an object of the present invention to overcome the deficiencies in the prior art to provide a breeding method for creating a new germplasm of ...
