[0003] At present, there are still few functional special soybean products in my country. There are only some "recipe soybeans" that are mixed with different types of soybeans on the domestic and foreign markets. The production method is that different types of soybeans are planted and produced separately, and then mechanically mixed in proportion. The process of this method is quite cumbersome, and the production cost is high, and functional special soybean varieties with high resistance to diseases and insect pests are even rarer

Abstract
The invention discloses a high resistance colored soybean variety breeding method and belongs to the technical field of disease-resistant special soybean breeding. The method comprises selecting a kind of a yellow soybean plant as a recurrent parent, respectively hybridizing the yellow soybean plant with a black soybean plant, a green soybean plant, a brown soybean plant and soybean plants with high lepidopterous larvae, cyst nematode disease and Cercosporidium sofinum, carrying out multi-generation backcrossing on the crossing offspring and the recurrent parent, carrying out hybridization on a colored plant and a pant resisting diseases and pests, carrying out screening on multi-generation seed coat and disease and insect pest resistance to obtain a soybean near-isogenic line with black seed coat, green seed coat and brown seed coat property characteristics and mixing the soybean near-isogenic line and the yellow soybean recurrent parent according to a ratio so that a high resistance colored soybean production variety is obtained. The high resistance colored soybean variety has a high yield and good resistance. Soybeans produced by the high resistance colored soybean variety comprise black soybeans, green soybeans, brown soybeans and yellow soybeans. The colored soybeans produced by the high resistance colored soybean variety have good colors, fragrances and tastes and good nutrition curative effects and have good nutrition and health functions.
Description
technical field [0001] The invention specifically relates to a method for breeding high-resistant colored soybean varieties, and belongs to the technical field of special soybean breeding. Background technique [0002] Soybean is native to China. It is a leguminous crop whose seeds are rich in plant protein and fat. Soybean has a wide range of uses. It is often used to extract soybean oil, make various soybean products and extract protein. The by-products after oil extraction Soybean meal is the most important protein raw material for the feed industry. Soybean gray spot, podworm, and cyst nematode are the main pests and diseases of soybean, which are frequent and sudden, and seriously affect the improvement of soybean yield and quality. Soybean gray spot is a common disease, which is caused by the fungus Cercospora sojae. It has an impact on the yield and quality of soybeans. Generally, the production of land will be reduced by 10-15%, and the production of severely damag...
