Embodiment

[0047] Embodiment: a kind of soybean breeding method of cold plasma treatment

[0048] The soybean breeding method treated with cold plasma can improve the germination ability of seeds, increase the main root length, increase the number of fibrous roots, increase the fresh weight of seedlings, increase the dry weight, increase the crude protein content, increase the crude fat content, increase the number of pods, and increase the number of seedlings. A new variety with the characteristics of increased grain number, increased yield, and enhanced disease resistance.

[0049] Specifically include the following steps:

[0050] (1) Collect breeding materials that meet the breeding objectives as key breeding objects

[0051] Hedou 21, Kedou 1, Weidou 7, Lindou 9, Hejiao 02-69, Zhonghuang 13, Hedou 19, Qihuang 34, Jiaoda 133, Huaxia 9 and other soybean varieties as a specific test material.

[0052] (2), the seed of the selected soybean variety of step (1) is placed in the cold pl...

Abstract

The invention relates to a method for breading soybeans by treating with cold plasmas. The method comprises the following steps: treating soybean seeds with the cold plasmas, observing according to apparent contact angles, sowing in good time, and culturing a new soybean variety with target characters. The soybean seeds are treated with the cold plasmas as follows: the raw materials of soybeans are subjected to non-ionizing radiation with the treatment power of 1-500w in an enclosed vacuum environment, wherein helium serves as a working medium. The apparent contact angles refer to the included angles among the gas, liquid and solid junctions of the soybean seeds treated with the cold plasmas and particularly between the gas interface and the liquid interface and between the solid interface and the liquid interface, and the apparent contact angles are 43-96 degrees. Because the soybean seeds are treated with the cold plasmas, the germinating capacity of the soybean seeds can be enhanced significantly, the growth character, biological character and yield character of the soybean seedlings can be improved, and the blank that the non-ionizing radiation technology can not be applied to soybean breading in the field of agricultural science is filled.

Description

technical field [0001] The present invention relates to a soybean breeding method, in particular to a cold plasma seed treatment technology to treat soybean seeds, through experiments and comparison combined with the observation of the apparent contact angle, to obtain the optimum treatment dosage and the optimum apparent contact angle, and apply it to The invention relates to a breeding method for selecting and breeding new soybean varieties, which belongs to the field of agricultural technology. Background technique [0002] The scientific name of soybean is max(L)Merrill, alias: soybean (including green beans, black beans, purple beans and spotted tea Giycine beans, etc.). Soybean belongs to Fabaceae, Papilionaceae, Glycine genus, Glycine max species. It is an annual herb native to my country. It has been cultivated in my country since ancient times and has a planting history of 5,000 years. Now it is widely planted all over the country, and it is produced in Northeast...
