Problems solved by technology

In addition, due to the lack of efficient breeding methods for black peanuts, only a single trait is emphasized in the selection of parents and offspring, that is, only for the selection of black seed coat peanuts, and the lack of comprehensive consideration of varieties has resulted in high-yielding and high-quality black peanut varieties especially scarce

Embodiment 1

[0034] A breeding method for black high-yielding peanut varieties, comprising the following steps:

[0035] 1) In the autumn of 2010, the high-yield peanut variety Yueyou No. 7 was selected as the female parent. The female parent has the following characteristics: high yield, disease resistance, and the growth of its progeny plants is more suitable for the climate and environment of Guangdong; the Heipi Nangai line 183 was selected It is the male parent, and the male parent has the following characteristics: the color of the seed coat is black, the fruit shape is large and plump, and the kernel rate of dried fruit is more than 75%; the F0 generation of peanut hybrid seeds is obtained through artificial cross-pollination. In order to facilitate artificial cross-pollination, the male parent was sown in an appropriate amount in the field according to conventional planting techniques; the female parent was planted in pots a week later, with 3 pots in total and 2 seeds in each pot. ...

Embodiment 2

[0063] A breeding method for black high-yielding peanut varieties, comprising the following steps:

[0064] 1) In the autumn of 2010, the high-yielding peanut variety Yueyou No. 7 was selected as the female parent. The female parent has the following characteristics: high yield, disease resistance, and the growth of its progeny plants is more suitable for the climate and environment of Guangdong; the black-skinned peanut variety Pearl Black was selected as the The male parent has the following characteristics: the color of the seed coat is black, the pods are medium in size and plump, and the kernel rate of dried fruit is more than 70%; the F0 generation of peanut hybrid seeds is obtained through artificial cross-pollination. In order to facilitate artificial cross-pollination, the male parent was sown in an appropriate amount in the field according to conventional planting techniques; the female parent was planted in pots a week later, with 3 pots in total and 2 seeds in each ...

Abstract

The invention discloses a breeding method for a high-yield black peanut variety. The breeding method is characterized by comprising the following steps: parent hybridization: performing artificial hybridization to fertilize a high-yield peanut variety serving as a female parent and a black seed husk variety serving as a male parent; character screening: seeding generations F0 to F2 one particle by one particle, performing selfing, and harvesting single plants; selection of the single plants: seeding generations F3 and F4 one particle by one particle, performing selfing, and selecting the single plants / strains according to an ideal peanut plant model before harvesting; harvesting pods from the selected single plants / strains, drying the pods, performing character detection on the pods according to the ideal peanut plant model, and retaining the single plants / strains of which the pods meet the conditions; harvesting of a target variety: performing yield detection and garden identification tests on the retained plants, comparing the retained plants with a contrast group, and selecting the variety with the yield higher than that of the contrast group. According to the breeding method, the problem of difficulty in combination of high yield, black seed husks and disease resistance is solved, the breeding period is greatly shortened, and the breeding method has important application value.

Description

technical field [0001] The invention relates to a breeding method, in particular to a breeding method of a black high-yielding peanut variety. Background technique [0002] Black peanut, that is, black seed coat peanut, is a kind of colored peanut, and its seed coat color is dark purple to dark black. But black peanuts are rich in nutrients, not only rich in crude protein, crude fiber and crude fat, but also contain calcium, potassium, copper, zinc, iron, selenium, manganese, 8 kinds of vitamins and 19 kinds of amino acids needed by the human body. Element. In addition, the black peanut seed coat contains a large amount of anthocyanin, which is a glycoside formed by anthocyanin and various monosaccharides in a natural state, and is a water-soluble natural pigment widely present in plants in nature. Studies have shown that anthocyanins exhibit various biological activities such as anti-inflammation, cardiovascular protection, and anti-tumor through their strong antioxidant ...
