Breeding method for novel peanut variety

Abstract

The invention provides a breeding method for a novel peanut variety. The breeding method comprises the following steps: with a high-yield disease-resistant line 025 spring / 26 as a female parent, hybridizing the female parent with a high-yield disease-resistant variety Shanyou 162 and carrying out F1-F4 continuous screening so as to breed a high-yield disease-resistant strain (025 spring / 26 * Shanyou 162) F5; with sweet osmanthus 22 as a female parent, hybridizing the female parent with 01 autumn / 813 and carrying out F1-F4 continuous screening so as to breed a high-yield high-oil high-kernel-percent excellent strain 3001 / 18; and with 3001 / 18 as a female parent, hybridizing the female parent with the (025 spring / 26 * Shanyou 162) F5 and carrying out F1-F9 continuous screening so as to breed a high-yield high-oil disease-resistant novel peanut variety sweet osmanthus 33. The breeding method for the novel peanut variety is simple and highly efficient; and the bred novel peanut variety has the advantages of a large per-plant-fruiting number, high yield, high oil and disease resistance and is especially applicable to cultivation and plantation in Guangxi Province, China.

Description

technical field [0001] The invention belongs to the technical field of peanut breeding, and relates to a breeding method for a new peanut variety, in particular to a breeding method for a new peanut variety suitable for cultivation in Guangxi. Background technique [0002] Peanut is one of the most important economic crops and oil crops in my country, and high yield has always been the main goal of peanut breeding. At present, my country has selected and bred some high-yield peanut varieties, but the yield of these peanut varieties is easily affected by the planting area and environmental climate, and peanut breeders in my country and the world have long been aiming at increasing peanut yield, while Insufficient attention has been paid to quality breeding such as high oil content and disease resistance breeding of peanuts, resulting in few high-yield, high-oil, disease-resistant peanut varieties bred. In addition, the application of peanut breeding methods is also relatively...

At present, my country has selected and bred some high-yield peanut varieties, but the yield of these peanut varieties is easily affected by the planting area and environmental climate, and peanut breeders in my country and the world have long been aiming at increasing peanut yield, while Insufficient attention has been paid to quality breeding such as high oil content and disease resistance breeding of peanuts, resulting in few high-yield, high-oil, disease-resistant peanut varieties bred

In addition, the application of peanut breeding methods is also relatively simple, mostly using the breeding process of parental hybridization, continuous selfing of hybrid offspring, selection of excellent single plants, strain comparison, strain comparison and regional testing, and there is no screening for a large number of hybrid combinations.
