Breeding method for high protein peanut

Abstract

The invention discloses a method for breeding high-protein peanut quality, which selects germplasm materials with good comprehensive characters and high-protein content to assemble parental combination; single plant with good comprehensive character is selected by breeding goal in early segregation generation, which is a high-yield pressure screening; the single plant with good comprehensive character is selected by the same standard in different segregation generation and the protein content of each single plant with good comprehensive character is measured; stable high-protein variety or strain with good comprehensive character is acquired through double pressure selection of multi-generation high-yield and high protein as well as directional breeding. The method for breeding high-protein peanut quality can carry out direct selection of protein content character; the invention is characterized by short breeding period, little blindness and high breeding efficiency. Peanut variety with high-protein content and good comprehensive character can be bred, which has good economic and social benefit.

Description

technical field [0001] The invention belongs to the technical field of crop sexual cross breeding, in particular to a high-protein peanut quality breeding method. Background technique [0002] Peanut is an important plant protein source for human beings, and the quality of peanuts undoubtedly has an important impact on human life and social economy. In recent years, the proportion of edible peanuts in my country has increased year by year, and high protein content has become the main breeding goal of edible processed peanuts. Peanut breeding researchers have also paid more and more attention to the innovation of high-protein breeding materials and the cultivation of high-quality, high-protein edible peanuts. [0003] Although my country's peanut breeding has achieved great success in improving yield and stress resistance, the high-protein breeding of peanuts is progressing slowly. From the previous breeding results, the average protein content of 35 peanut varieties bred an...

AI Technical Summary

Problems solved by technology

Since the high-protein traits of mutant individuals (a single seed) cannot be directly selected in the segregation generation, the high-protein genes in the mutant population cannot be recombined and accumulated through multi-generation selection, and the high-protein genes cannot be integrated into traits excellent production varieties

Due to the inability to conduct directional selection and breeding for high-protein traits, the probability of obtaining high-protein varieties is extremely low

It can be seen that it is difficult to integrate the high-protein genes in the germplasm resources into the production varieties in the current conventional peanut breeding technology.
