Embodiment

[0022] Embodiment, a kind of breeding method of high-yield and high-oil peanut variety is (1) according to ideal character selection good performance variety as target variety; and the epistasis genetic effect and the characteristics of the additive genetic effect of peanut oil content select high-yielding, high-oil peanut varieties as the selection targets of parents; The scope of high-oil gene selection increases; (4) Utilize the characteristic that the two ends of the microsatellite DNA in the genome are conserved single-copy sequences, design a pair of specific primers according to the sequences at these two ends, and transfer the core microsatellite DNA therebetween to The sequence is amplified, and its length polymorphism can be obtained by using electrophoresis analysis technology. According to its polymorphism, the selected high-yield and high-oil peanut varieties are clustered to find out the genetic relationship between different varieties; (5 ) make full use of dist...

Abstract

The invention discloses a method for breeding high-yield high-oil peanut species. In the method, a genetic relationship of the selected high-yield high-oil peanut species is found out by an SSR (Simple Sequence Repeat) molecule marker technology; the species with distant hybrid advantages and larger selection difference is used as a parent for preparing cross combination; the variation frequency is expanded by radiation effect, and the selecting range of a high-yield high-oil gene is expanded; the genetic linkage of an adverse gene is broken down by applying hybridization, and the recombination, polymerization and complementation of high yield, high oil and resistance are realized; an individual plant is directionally selected by using ideal characters as a target in stable generation; and the individual plant is inbred for one generation, a plant system with complete and ideal characters is further selected, and the high-yield high-oil plant system is obtained. The invention has the characteristics of rapidly breeding the high-yield high-oil peanut new species and having simple method and high operability.

Description

technical field [0001] The invention belongs to the technical field of peanut breeding, in particular to a method for breeding high-yield and high-oil peanut varieties. Background technique [0002] Peanut is an important oil crop and economic crop in my country. High-yield breeding has always been the main goal of peanut breeding and the eternal theme of peanut breeding. Compared with rapeseed, soybean and other oil crops, peanut has the advantages of high yield and high oil content, which plays an indispensable role in increasing domestic vegetable oil production. However, currently widely planted peanut varieties have low oil content and cannot meet the needs of the market. Therefore, Breeding of high-oil peanut varieties has also become one of the main goals of peanut breeding. During the Ninth Five-Year Plan period, my country bred some high-yielding and disease-resistant peanut varieties, which played an important role in increasing my country's peanut production. How...
