High oil peanut quality breeding method

Abstract

The invention provides a high oil peanut quality breeding method which comprises, combining parental generation combination by selecting seeds with good comprehensiveness and high oil content, selecting fine strains at early stage generation, which is high yield pressure screen selecting, determining oil content in each seed of the single strain, screening seeds with high oil content for cultivation on next generation, which is high oil pressure screening, finally selecting fine single strain and determining oil content for each seed of the fine single strain for different separated generations, and accomplishing high yield and high oil pressure selection and oriental cultivation.

Description

technical field

[0001] The invention belongs to the technical field of sexual hybrid breeding of crops, in particular to a quality breeding method for high-oil peanuts. Background technique

[0002] Genetic improvement of peanuts using sexual cross breeding technology has achieved great success in increasing yield, enhancing disease resistance and adaptability, etc., but progress in improving peanut quality has been slow and the results have been extremely limited. The reasons for this situation Breeders can directly select traits such as yield and disease resistance in the segregation generation, but cannot select quality traits, so they cannot conduct directional breeding. Therefore, it is difficult to improve the quality traits of peanuts through sexual cross breeding. The current breeding techniques aimed at improving peanut oil content are limited to the assembly of high-oil parent combinations and the indirect selection of hybrid progenies bas...
