Embodiment 1

[0013] A method for cultivating peanuts with variegated seed coats and high oleic acid, comprising the following steps: hybridizing the female parent 1 powder-skinned high oleic acid peanuts with the male parent 1 variegated common peanuts to obtain the first generation offspring F 1 , the F 1 F 2 , F 2 The F 3 Once again, single plants with good stability and performance were screened out. 4 Variety test was carried out on strains, candidate varieties were screened, and F 5 form varieties.

Abstract

The invention discloses a cultivation method for high-oleic-acid peanuts with spotted seeds and peels. The cultivation method for high-oleic-acid peanuts with spotted seeds and peels comprises the following steps: separately selecting a pink-peel high-oleic-acid peanut and a spotted common peanut as a female parent and a male parent, carrying out hybridization to obtain F1, erasing false hybrid from the generation F1 and then carrying out selfing to obtain F2, screening a single strain with spotted seeds and peels from F2 by using a KASP label, screening F3 again to obtain a stable good-performance single strain with spotted seeds and peels, carrying out variety test on F4 line, and screening a candidate variety to finally obtain a F5 formation variety. The appearance of the cultivated high-oleic-acid peanuts with spotted seeds and peels is different from that of common pink-peel peanuts, the cultivated high-oleic-acid peanuts with spotted seeds and peels are conveniently distinguishedfrom common peanuts, and thus, the high-oleic-acid peanuts can be utilized well.

Description

technical field [0001] The invention relates to the technical field of peanut breeding, in particular to a method for cultivating peanuts with variegated seed coats and high oleic acid. Background technique [0002] Peanut is one of the important oil crops widely planted in the world. China is the largest producer of peanut in the world, and its annual output ranks first in the world. The oleic acid and linoleic acid in the total unsaturated fatty acids in ordinary peanuts reached 1:1. Among them, oleic acid can not only increase the level of high-density lipoprotein cholesterol in the human body, remove excessive triglycerides, but also effectively prevent low-density lipoprotein cholesterol from forming lipid peroxides, reduce the existence of free radicals, and stimulate the function of immune cells. Inhibit "oncogenes", thereby greatly reducing the incidence of cardiovascular and cerebrovascular diseases and the risk of cancer. However, linoleic acid is prone to oxidat...
