Embodiment 1

[0040] A method for quickly cultivating high-oil, high-oleic-acid salt-tolerant peanuts, comprising the following steps:

[0041] (1) Using peanuts with high oil (more than 55% oil content) as the female parent and peanuts with high yield and high oleic acid (more than 75% oleic acid content) as the male parent, carry out hybridization;

[0042] (2) The F1 generation seeds obtained after hybridization are tested for hybrid genes to screen true hybrids and eliminate false hybrids;

[0043] Because of the hybridization process, the female parent is often incompletely castrated, and the pollen in the remaining anthers will pollinate and fertilize the pistil of the same flower, resulting in self-fertilization, and the seeds it bears are pseudohybrids. The high oleic trait is controlled by 2 pairs of recessive genes. The F1 generation seeds were detected by molecular assisted means, and if the gene sequence was the same as that of the high-oil female parent, it was a false hybrid....

[0062] A method for quickly cultivating high-oil, high-oleic-acid salt-tolerant peanuts, comprising the following steps:

[0063] (1) Using peanuts with high oil (more than 55% oil content) as the female parent and peanuts with high yield and high oleic acid (more than 75% oleic acid content) as the male parent, carry out hybridization;

Abstract

The invention provides a method for rapidly cultivating high-oil high-oleic-acid salt-tolerant peanuts, and belongs to the technical field of new peanut variety cultivation. High-oil peanuts are used as female parents, high-yield high-oleic-acid peanuts are used as male parents, and hybridization is carried out; hybrid gene detection is performed on F1-generation seeds obtained after hybridization, true hybrids are screened, and false hybrids are eliminated; the F1-generation seeds screened through gene detection are subjected to generation adding in Hainan in November of the current year and are sowed in a field, and hybrid F2-generation seeds are harvested according to a single plant after the seeds are mature in March of the next year; the oil content and the oleic acid content of the F2-generation seeds are detected in a non-destructive mode through a near-infrared instrument, and high-oil high-oleic-acid seeds with the oil content being 55% or above and the oleic acid content being 75% or above are screened; yield identification is carried out on a selected salt-tolerant high-oleic-acid strain, and yield comparison test and salt tolerance identification are carried out on the selected strain. According to the method for rapidly cultivating the high-oil high-oleic-acid salt-tolerant peanuts, a high-oil high-oleic-acid salt-tolerant peanut variety can be rapidly obtained, and the breeding period is shortened by 3 years compared with a common breeding method.

Description

technical field [0001] The invention belongs to the technical field of cultivating new varieties of peanuts, and in particular relates to a method for quickly cultivating high-oil, high-oleic-acid and salt-tolerant peanuts. Background technique [0002] my country is a country in short supply of edible oil, the self-sufficiency rate is only 30%, and 70% depends on imports. Peanuts account for 48 percent of total oil crop production. 50% of the peanuts produced in my country are used for processing peanut oil. The low self-sufficiency rate of edible oil in my country is largely due to the shortage of arable land in my country. There are about 1.5 billion mu of barren saline-alkali land in my country, and the research and application of crops planted in saline-alkali land is very important. Breeding salt-tolerant peanut varieties with high oil content is the main way to alleviate the pressure of edible oil shortage in my country. Ordinary peanut varieties cannot grow norma...
