Problems solved by technology

In addition, oleic acid has only one double bond, its chemical structure is relatively stable, and its antioxidant capacity is strong, so it is not easy to deteriorate during refining, storage and frying; linoleic acid contains two double bonds, which is easy to oxidative rancidity, making peanut products easy Odor, short shelf life of peanut seeds and processed products

Abstract

The invention discloses a high oleic and high yield peanut breeding method, and belongs to the field of plant breeding. The method comprises the following steps that (1), high yield peanut varieties are selected as a female parent, high-oleic peanut varieties are selected as a male parent, hybridization is conducted, and a high yield and high-oleic F1 generation is obtained; (2), the F1 generationis subjected to selfing after false hybrids is removed, and an F2 generation is obtained; (3), high-oleic and high yield single plants are screened out, selfing is conducted, and an F3 generation isobtained from the F2 generation; (4), stable high oleic and high yield single plants are screened out from the F3 generation and subjected to backcross with the high yield peanut parent in step (1), and an F4 generation is obtained; (5), high oleic and high yield single plants are screened out from the F4 generation and subjected to backcross with a high oleic peanut male parent, and an F5 generation is obtained; (6), F5 is subjected to selfing for four consecutive generations, an F6 generation, an F7 generation, an F8 generation and an F9 generation are obtained, and the F8 generation is thenew variety of the high oleic and high yield peanut. By means of the method, the new peanut variety of the peanut high in yield and oleic acid content is bred.

Description

technical field [0001] The invention belongs to the field of plant breeding, and in particular relates to a breeding method for peanuts with high oleic acid and high yield. Background technique [0002] my country is the world's largest peanut producer, consumer and exporter. The total output of peanuts accounts for 50% of the total output of oil-bearing crops in the country, and the total output ranks first among all oil-bearing crops, accounting for 43% of the total output of peanuts in the world, ranking first in the world. Therefore, peanuts have an important position and role in my country's national economy. [0003] Peanut oil mainly contains two fatty acids, namely oleic acid and linoleic acid. Oleic acid is the main fatty acid in peanut oil, accounting for 39% to 49% of the total peanut fatty acid. Oleic acid has high nutritional value. It can reduce harmful cholesterol in human body lipid metabolism, but maintain the level of beneficial cholesterol, thereby slowi...
