Embodiment 1

[0011] The high-oleic peanut variety Huayu 19 was used as the female parent, and the high-protein peanut variety Yueyou 79 was used as the male parent to obtain the first F1 generation, and the high-oleic peanut variety Luhua 11 was used as the female parent. Variety Luhua 14 was used as a male parent collocation to obtain the second F1 generation, the first F1 generation was used as the female parent, and the second F1 generation was used as the male parent collocation to obtain the third F1 generation. The third F1 generation continuously selfed to obtain F2, F3, F4, F5 generations. Starting from F3 generation, each generation selects high-oleic acid, high-protein and high-yielding single plants for self-reproduction. While selecting high-yield single plants, use The near-infrared diffuse reflectance spectroscopy non-damage selection technology carries out high-oleic acid and high-protein non-damage selection, and self-crosses individual plants with high oleic acid, high prote...

Embodiment 2

[0013] The high-oleic peanut variety Huayu 32 was used as the female parent, and the high-protein peanut variety Fuhua 10 was used as the male parent collocation to obtain the first F1 generation. The high oleic peanut variety Pukehua 15 was selected as the female parent. , The high-yield peanut variety (Luhua No. 9) is used as a male parent collocation to obtain the second F1 generation, the first F1 generation is used as the female parent, and the second F1 generation is used as the male parent collocation to obtain the third F1 generation. The third F1 generation continuously selfed to obtain F2, F3, F4, F5 generations. Starting from F3 generation, each generation selects high-oleic acid, high-protein and high-yielding single plants for self-reproduction. While selecting high-yield single plants, use The near-infrared diffuse reflectance spectroscopy non-damage selection technology carries out high-oleic acid and high-protein non-damage selection, and self-crosses individual...

Abstract

The invention discloses a high-oleic-acid, high-protein and high-yield peanut breeding method, which comprises the following steps of selecting high-oleic-acid peanuts and high-protein peanuts for hybridization to obtain a first F1 generation, selecting other high-oleic-acid peanuts and high-yield peanuts for hybridization to obtain a second F1 generation, and taking the first F1 generation as a female parent and the second F1 generation as a male parent for collaborative hybridization to obtain a third F1 generation; and using the third F1 generation for continuous selfing to obtain an F2 generation, an F3 generation, an F4 generation and an F5 generation, selecting high-oleic-acid, high-protein and high-yield individual plants of each generation for selfing breeding from the F3 generation, making line comparisons from an F6 generation, selecting excellent lines to enter an appraisal garden and obtaining a new high-oleic-acid, high-protein and high-yield peanut variety. Not only is the yield of the peanut variety which is bred by using the method high, but also the contents of oleic acid and protein are also high, the peanuts are suitable for processing and export, and the economic benefit and the social benefit are remarkable.

Description

technical field [0001] The invention relates to a peanut breeding method and belongs to the technical field of peanut breeding. Background technique [0002] Peanut is the main oil crop and economic crop in my country. The main fatty acids in peanut are oleic acid and linoleic acid, and linoleic acid is the root cause of oil spoilage. In ordinary peanuts, the content of oleic acid is about 45%, and the content of linoleic acid is about 35%. Peanut oil made from ordinary peanuts contains a large amount of linoleic acid. If no preservatives are added, it will be easily spoiled; if preservatives are added, it will have adverse effects on human health. In the past ten years, increasing the oleic acid content of peanuts and reducing the linoleic acid content of peanuts has been a research hotspot for peanut breeders to improve peanut quality. Oleic acid can lower the amount of total blood cholesterol and bad cholesterol, but not the amount of good cholesterol. In the field of ...
