Abstract

The invention discloses a breeding method of a broad-resistance green soybean variety, and belongs to the technical field of soybean breeding for disease resistance. The breeding method comprises the following steps of hybridizing a high-yield and high-quality soybean variety with soybean varieties for highly resisting frogeye leaf spot, mosaic virus disease, downy mildew and cyst nematode disease; re-hybridizing filial generations two by two; evaluating and screening seed coat colors and disease resistance of multiple generations to breed the broad-resistance green soybean variety which can simultaneously resist four diseases and are excellent in other agricultural and yield characters. The variety has excellent agricultural and yield characters, and can resist the frogeye leaf spot, the mosaic virus disease, the downy mildew and the cyst nematode disease of soybean.

Description

technical field [0001] The invention specifically relates to a breeding method for wide-resistant green soybean varieties, and belongs to the technical field of soybean disease-resistant breeding. Background technique [0002] Green beans are rich in unsaturated fatty acids and soybean phospholipids, which can maintain the elasticity of blood vessels, strengthen the brain and prevent the formation of fatty liver. Studies have shown that green beans are rich in various antioxidant components and can also eliminate inflammation. Green beans can provide the human body with two flavonoid antioxidants, catechin and epicatechin. These two substances can effectively remove free radicals in the body, prevent diseases caused by free radicals, delay the aging of the body, and have anti-inflammatory and broad-spectrum antibacterial effects. Lima beans also contain two carotenoids: alpha-carotene and beta-carotene. In 2010, according to a 14-year follow-up study, the US Centers for D...
