Embodiment 1
[0016] 1) Longdou 4, a high-oil, high-yield, and high-quality soybean variety, was used as the recurrent parent (variety R), and it was mixed with Changnong 20 (variety A), which is highly resistant to soybean downy mildew, and highly resistant to soybean mosaic virus disease and bacterial spot, respectively. Variety Jinong 32 (variety B), variety Jilin No. 16 (variety C) with high resistance to podworm, Hefeng 29 (variety D) with high resistance to soybean gray spot, and Kangxian 1 (variety E) with high resistance to cyst nematode disease ) to get 5 hybrid F 1 , respectively with F 1 -A, F 1 -B,F 1 -C, F 1 -D, F 1 -E means;
[0017] 2) Plant F 1 -A, F 1 -B,F 1 -C, F 1 -D, F 1 -E each 10 plants, self-bred to get F 2 Generation F 2 -A, F 2-B,F 2 -C, F 2 -D, F 2 -E, Plant F 2 Generation, each combination planted 60 plants, F 2 Identify the types of pests and diseases resistant to each combination on behalf of each combination, and only identify the types of pes...
Embodiment 2
[0023] 1) The high-oil, high-yield and high-quality soybean variety Pingdou No. 1 was used as the recurrent parent (variety R), and the high-resistant soybean downy mildew variety Changnong 20 (variety A), and the high-resistant soybean mosaic virus disease and bacterial spot disease were used as the recurrent parent. Variety Jinong 32 (variety B), variety Jilin No. 16 (variety C) with high resistance to podworm, Hefeng 29 (variety D) with high resistance to soybean gray spot, and Kangxian 1 (variety E) with high resistance to cyst nematode disease ) to get 5 hybrid F 1 , respectively with F 1 -A, F 1 -B,F 1 -C, F 1 -D, F 1 -E means;

Abstract
The invention discloses a breeding method of a disease-insect-resistant soybean variety, and belongs to the technical field of soybean disease and insect resistance breeding. The method comprises the steps that a high-oil and high-yield soybean variety wing bean No.4 or flat bean No.1 is taken as a recurrent parent to be hybridized with a high downy-mildew-resistant variety, a high mosaic-virus-resistant variety, a high bacterial-speck-resistant variety, a high budworm-resistant variety, a high grey-speck-disease-resistant variety and a high cyst-nematode-disease-resistant variety separately, five kinds of main soybean disease and insect source-resistant genes are guided into the high-oil and high-yield soybean varieties in the same genetic background through a synchronous backcrossing method, five disease-insect-resistant near-isogenic lines which can highly resist corresponding diseases and insects and have the agronomic and yield characteristics highly consistent with those of the recurrent parent are bred, seeds of the five disease-insect-resistant near-isogenic lines are mixed according to the ratio of 1:1:1:1:1, and then seeds of the high-resistant soybean variety for production are obtained. The disease-insect-resistant soybean variety is a mixed variety, and after the seeds are planted, the plant leaf forms and the agronomic characteristics are uniform, the yield is high, and the resistance is good.
Description
technical field [0001] The invention specifically relates to a method for breeding soybean varieties resistant to diseases and insect pests, and belongs to the technical field of soybean breeding for resistance to disease and pests. 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 downy mildew, mosaic virus disease, bacterial spot, borer, gray spot, and cyst nematode are the main diseases and insect pests of soybean, which are frequent and sudden, and seriously affect the improvement of soybean yield and quality. Soybean downy mildew is widely distributed in soybean producing areas in the world, and it is more common in Northeast China and North Chin...
