Problems solved by technology

[0003] Soybean is a short-day temperature-loving plant, and its growth rate can be accelerated by artificial short-day, high-temperature treatment, and early pod picking. However, due to the high cost of artificially adjusting light and temperature, the planting scale of breeding materials is limited, and artificial light Treatments are not widely used in these soybean breeding

Embodiment 1

[0025] Embodiment 1, live direct seeding of fresh grain shortens soybean growth cycle

[0026] 1. Test materials

[0027] The inventors of the present invention conducted a breeding experiment using three soybean varieties as test materials.

[0028] The three soybean varieties are as follows:

[0029] 1. Zhonghuang 70 is a conventional summer soybean variety in Shandong Province. Relevant information of Zhonghuang 70: scientific name Glycine max(L.)Merr.; approval number: Lu Nong Shen 2013021; ​​breeding unit: Institute of Crop Science, Chinese Academy of Agricultural Sciences;

[0030] 2. Information about Zhonghuang 909: scientific name Glycine max(L.)Merr., strain material of Institute of Crop Science, Chinese Academy of Agricultural Sciences, breeding target area is Hulun Buir City, Inner Mongolia Autonomous Region; female parent is Heihe Branch, Heilongjiang Academy of Agricultural Sciences The new soybean line Hei 05-38 was bred. The male parent is the new soybean li...

Abstract

The invention discloses a method for shortening the soybean growth period. The method includes the steps of stripping off seeds in pods from the R6.0 period to the R7.0 period and then directly sowingthe seeds, wherein the pods in the R6.0 period are pods where seeds just fulfill seed pits of pod walls after soybean plants reach the grain fulfilling period, and the pods in the R7.0 period are pods where pot walls just turn to mature color and luster but not become round yet after the soybean plants reach the physiological maturity period. By means of the method, one generation of plantation can be completed within a short period of time (90 days), the generation process of crops is greatly accelerated, the seed culture age limit is shortened, the seed culture efficiency is effectively improved, and the seed culture process is accelerated. The method has great application value.

Description

technical field [0001] The invention belongs to the field of plant breeding, in particular to a method for shortening the growth cycle of soybeans. Background technique [0002] Conventional crossbreeding is the most widely used and effective means of crop breeding. Its basic procedure is to use methods such as interbreeding to create variation, to achieve gene homozygosity through continuous selfing, and to select homozygotes that meet the needs, so as to breed new varieties. method. In the process of cross-breeding, after crossing the parents to produce the F1 generation, it is necessary to self-purify for 4 to 5 generations before selecting important traits such as yield, until a stable genetic line is selected, and then carry out line identification and variety tests to obtain Varieties of specificity, consistency, stability and economic utility. It usually takes more than ten years to select and breed a new crop variety from the preparation of a hybrid combination to ...
