A kind of breeding method of high oleic acid disease-resistant peanut

A high oleic acid, peanut technology, applied in the directions of botanical equipment and methods, applications, plant genetic improvement, etc., can solve the problems of less emphasis on breeding and disease resistance breeding, and few varieties with high oleic acid, high yield and disease resistance, etc. Achieve the effect of good comprehensive traits, good economic and social benefits, and small blindness

Problems solved by technology

[0005] However, for a long time, peanut breeders in my country and the world have always focused on improving peanut yield, and paid less attention to quality breeding such as high oleic acid and disease resistance breeding, and there are not many varieties with high oleic acid, high yield and disease resistance

Embodiment 1

[0012] The first F1 generation was obtained by crossing the peanut variety Yueyou 79 resistant to bacterial wilt and the high oleic peanut variety Luhua 11 as the male parent. The hybrid F1 generation was used as the female parent and the high oleic peanut variety Luhua 11 was used as the male parent for backcrossing, and the first generation of backcrossing BC1F1 was obtained. From the BC1F1 generation, the bacterial wilt-resistant plants were selected as the female parent and Luhua 11 was backcrossed again to obtain BC2F1, and the bacterial wilt-resistant plants were selected from the BC2F1 generation as the female parent. Ben once again backcrossed with Luhua 11 to obtain BC3F1, and self-crossed bacterial wilt resistant plants from BC3F1 to obtain BC3F2, and selected plants with high oleic acid content, high yield, and strong bacterial wilt resistance from BC3F2 as female parents and leaf resistant plants. The spot disease variety Huayu 19 was crossed with the male parent, a...

Embodiment 2

[0014] The first F1 generation was obtained by crossing the peanut variety Zhonghua No. 6 resistant to bacterial wilt as the female parent and the high-oleic peanut variety Huayu No. 19 as the male parent. The hybrid F1 generation was used as the female parent and a high-oleic peanut variety Huayu No. 19 was used as the male parent for backcrossing, and the backcross generation BC1F1 was obtained. Plants resistant to bacterial wilt were selected from the BC1F1 generation as the female parent and Huayu No. 19 was backcrossed again to obtain BC2F1, and bacterial wilt resistance was selected from the BC2F1 generation. The plant was used as the female parent and backcrossed with Huayu No. 19 to obtain BC3F1. From BC3F1, selected plants resistant to bacterial wilt were self-crossed to obtain BC3F2. From BC3F2, the plants with high oleic acid content, high yield and strong resistance to bacterial wilt were selected as The female parent was crossed with the leaf spot resistant variety...

Abstract

The invention discloses a method for breeding high-oleic-acid disease-resistance peanuts, which comprises the following steps: obtaining first F1 generation by crossing bacterial wilt resistant peanuts and high-oleic-acid peanuts; backcrossing a crossing F1 generation with high-oleic-acid peanuts to obtain backcrossing first generation BC1F1, backcrossing bacterial wilt resistant plants and high-oleic-acid peanuts from BC1F1 to obtain BC2F1, backcrossing bacterial wilt resistant plants and high-oleic-acid peanuts from BC2F1 to obtain BC3F1, performing selfing of bacterial wilt resistant plants from BC3F1 to obtain BC3F2, crossing plants selected from BC3F2 with a leaf spot resistant variety to obtain a second crossing F1; and performing continuous selfing starting from the second F1 generation to obtain F2, F3, F4 and F5 generations, entering an identification nursery from F6 generation, performing quality identification and obtaining high-oleic-acid disease-resistance peanuts. The peanut variety bred by the method has high oleic acid content and high disease resistance, and therefore is suitable to be planted in areas where peanut diseases occur frequently. The method has remarkable economic and ecological benefit.

Description

Technical field [0001] The invention involves a new method of breeding of high -hydrocarbon disease resistance and peanuts, which belongs to the field of peanut genetic breeding technology. Background technique [0002] The peanuts are generally serious and serious in Southeast Asian countries such as Indonesia, Vietnam, and some African countries. They are mainly distributed in the provinces and regions south of the Yangtze River in my country. It is more severe, and there are small area in Hebei, Liaoning and other provinces in the north.The incidence is generally 10%-20%, and the severe ones are more than 50%, and even the whole piece of death will cause major economic losses to farmers. [0003] Peanut leaf spots include brown spot disease and dark spots.Belly spots are also called "early spot disease"; black spot disease is also called "black gangrene".These two diseases are all over the main flower production areas in my country.Mixed mixing occurs on the same blades of the...
