Embodiment 1

[0019] The invention provides a method for breeding anthocyanin-synthesized fresh corn inbred lines, comprising the following steps:

[0020] (1) cross the corn inbred line 0414 with black pericarp and the corn inbred line 3370 with colorless pericarp to obtain the F1 generation;

[0021] (2) The F1 generation is self-bred and reserved to obtain the F2 generation;

[0022] (3) Sowing the F2 generation mixed, ignoring the color traits of the whole ear, selecting a single plant with excellent phenotypic traits such as plant type, leaf type, and disease resistance to carry out selfing and retaining a single ear to obtain the F3 generation;

[0023] (4) Plant the F3 generation according to the panicle row, select a single panicle with black skin of the whole panicle in the panicle row, and select a single plant with good phenotypic properties such as plant type, leaf type, and disease resistance for selfing to retain a single panicle, Obtain the F4 generation;

[0024] (5) Plant...

Embodiment 2

[0029] The invention provides another method for breeding anthocyanin-synthesized fresh corn inbred lines, comprising the following steps:

[0030] (1) The maize inbred line 0425 with purple pericarp was crossed with the maize inbred line 3370 with colorless pericarp to obtain the F1 generation;

[0031] (2) The F1 generation is self-bred and reserved to obtain the F2 generation;

[0032] (3) Sowing the F2 generation mixed, ignoring the color traits of the whole ear, selecting a single plant with excellent phenotypic traits such as plant type, leaf type, and disease resistance to carry out selfing and retaining a single ear to obtain the F3 generation;

[0033] (4) Plant the F3 generation according to the panicle row, select a single panicle with black skin of the whole panicle in the panicle row, and select a single plant with good phenotypic properties such as plant type, leaf type, and disease resistance for selfing to retain a single panicle, Obtain the F4 generation;

Abstract

The invention discloses a breeding method of a fruit peel anthocyanin synthesized fresh corn selfing line. The method comprises the steps of carrying out hybridization line selection on a corn selfing line with peel rich in anthocyanin and a corn selfing line with colorless peel, carrying out selfing seed stock on a generation F1, ignoring the seed grain color character of a generation F2, carrying out selfing on single plants with relatively good phenotypic characters such as plant type, leaf type and disease resistance, preserving single spikes, concerning the seed grain color character from a generation F3, planting according to a head progeny row, simultaneously considering phenotypic characters such as the plant type, the leaf type and the disease resistance, selectively preserving single spikes with purple or black full-spike peel, planting according to the single spikes, continuing selfing for four generations, and preserving plant row with consistent characters and purple or black full-spike peel, so as to obtain the stably inherited fruit peel anthocyanin synthesized fresh corn selfing line. The breeding method can be used for assisting cultivation and authentication of the corn selfing line rich in anthocyanin and the breeding of new types of fresh corns rich in anthocyanin and has very good application prospects.

Description

technical field [0001] The invention relates to the technical field of crop genetics and breeding, in particular to a method for breeding anthocyanin-synthesized fresh corn inbred lines. Background technique [0002] Anthocyanin is a water-soluble natural pigment synthesized in plants. Anthocyanin is a powerful antioxidant that can bring many benefits to the human body, such as protecting the human body from free radical damage, strengthening blood vessels Elasticity, improved circulation and more. Anthocyanins have been found in a variety of food crops, such as corn, rice, sorghum, purple sweet potato and so on. [0003] Fresh purple, black and other colorful corns are rich in anthocyanins, because of their high anthocyanins content, fat, protein, iron, calcium, amino acids and other nutrients, they are considered as health-care golden food in fresh corns . Peel rich in anthocyanins is a kind of colorful fresh corn, which is favored because of its high anthocyanin conten...
