High-oleic-acid peanut high-yield planting method

Abstract

Provided is a high-oleic-acid peanut high-yield planting method. The method includes the steps that (1) a high-yield peanut variety is selected as a female parent, a high-oleic-acid peanut variety isselected as a male parent, the selected female parent and the selected male parent are placed in a wet culture dish, hybridization is conducted in a 25 DEG C illumination incubator, and a F1 generation with high yield and high oleic acid is obtained; (2) false hybrids are removed from the F1 generation in the step (1), and selfing is conducted to obtain an F2 generation; (3) F2 in the step (2) isinduced to generate calluses; (4) the F2 generation calluses in the step (2) are screened, and the calluses with positive screening results are cultured into seedlings; and (5) sterilization treatmentis conducted on F2 living seeds in the step (4), and treatment is conducted with 60Co-gamma rays after treatment. The adaptability and the yielding ability of the cultivated high-quality peanut seedsare guaranteed through earlier-stage pretreatment, the economic benefit, the social benefit and the ecological benefit are remarkable, and the breeding requirement can be met.

Description

Technical field[0001]The present invention relates to the field of planting technology, and is specifically a high yield of high yaw peanrate.Background technique[0002]my country is the world's largest peanut production, consumption and exporting country. The total production of peanns is 50% of the national oil crops, and the total output is the first of the oil crops, accounting for 43% of the World Peanut Production, ranking first in the world. Therefore, peanuts have an important status and role in our national economy.[0003]Peanut oil mainly contains two fatty acids, ie oleic acid and linoleic acid. Oleic acid is the main fatty acid in peanut oil, accounting for 39% to 49% of the total amount of peanut acid, and the nutrient value of oleic acid is high. It can reduce harmful cholesterol in human lipid metabolism, but maintain a good cholesterol level, thereby slowing down Atherosclerosis, effectively prevent the occurrence of cardiovascular and cerebrovascular diseases such as ...

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
