Embodiment 1

[0029] 1. Breeding of Shennong ZS717 purple corn inbred line

[0030] The foreign purple corn material Stock 6 with purple plants, bracts, grains and cobs was used as the female parent, and the Chinese white waxy corn Zhongnuo 1 was used as the male parent to breed ZS717 purple corn through the two-ring breeding method. Corn inbred lines:

[0031] F1 selects a single plant with purple plants, bracts, peels, and cobs for selfing. After harvest, the endosperm is selected by the minimally invasive single-seed identification method, and waxy, white single-seeds are selected;

[0032] F2~F3, select according to the method of F1;

[0033] F4, select the single plant selfing of plant, bract leaf, pericarp, and cob purple, and obtain endosperm waxy quality, endosperm white homozygous ear after harvesting;

[0034] F5, select the homozygous plants, bracts, pericarp, axis color, and Bainuo homozygous ears for selfing, and obtain excellent single plants;

[0035] F6, carrying out str...

Embodiment 2

[0041] 1. Breeding of Shennong ZF740 purple corn inbred line

[0042] Based on the population materials containing purple plants, purple husk leaves, purple peel, purple cobs, purple filaments and waxy traits, purple maize inbred lines were bred through one-ring breeding method:

[0043] S1, select a single plant with purple purple plants, bracts, peels, and cobs for selfing; after harvesting, identify the grains with a minimally traumatic single-seed identification method to obtain a single-seed homozygous for waxy endosperm;

[0044] S2, select a single plant with purple purple cobs, bracts, peels, and cobs for selfing; identify the grains of the harvested single ears with a micro-trauma single-seed identification method, and obtain single ears and single grains that are homozygous for waxy quality and white endosperm;

[0045] S3, select the single plant selfing of plant, bract leaf, pericarp, and cob purple; identify the grain of the harvested ear with the method of micro-...

Embodiment 3

[0055] 1. Breeding of Shennong ZS513 purple corn inbred line

[0056] The foreign purple corn material Stock 6 with purple plants, bracts, grains and cobs was used as the female parent, and the Chinese white waxy corn Zhongnuo 1 was used as the male parent to breed ZS717 purple corn through the two-ring breeding method. Corn inbred lines:

[0057] F1 selects a single plant with purple plants, bracts, peels, and cobs for selfing. After harvesting, use the micro-trauma identification method to identify single grains, and select single grains with white endosperm and non-waxy quality;

[0058] F2~F3, select according to the method of F1;

[0059] F4, select a single plant with purple purple cobs, bracts, peels, and cobs for selfing, and obtain a homozygous ear with white endosperm and non-waxy quality after harvest;

[0060] F5, obtain homozygous panicle rows with homozygous plant, bract leaf, pericarp, axis color, and white endosperm, and select excellent single plants for se...

Abstract

The invention relates to a selective breeding technique of an anthocyanin type purple corn, comprising the following steps: pyramiding anthocyanin dominant genes of a plurality of locus, and enablingthe anthocyanin dominant genes of the locus to be homozygous; then pyramiding large subtending leaves, high yielding, excellent quality and adversity character and breeding purple corn or purple waxycorn inbred line which has high anthocyanin content by early generation selection and a minimally invasive single kernel identification method; and selectively breeding the anthocyanin type pure purple genotype homozygous or dominant heterozygous corn--the purple waxy corn and the purple corn by matching the purple waxy corn with the purple waxy corn, matching the purple waxy corn with the purplecorn, matching the purple corn with the purple corn or matching the purple corn with other purple recessive character corns. A prepared single cross hybrid has the advantages as follows: 1. seed cases, aleurone layers, rhachises, the subtending leaves, filaments, tassels, anthers are purple and rich in anthocyanin, and stalks, medulla, leaf veins and leaves present purple colors of different degrees and all contain the anthocyanin; 2. the single cross hybrid not only can be used for producing the anthocyanin but also can be used as a fresh food; and 3. the single cross hybrid has high yieldingand can be cultivated on all soils which are suitable for common corns.

Description

technical field [0001] The invention belongs to corn breeding technology, in particular to a kind of breeding technology of anthocyanin type purple corn. Background technique [0002] Anthocyanins are powerful antioxidants. In order to eliminate the damage of free radicals to the human body, prevent and treat various diseases related to free radicals, such as cancer, heart disease, high blood pressure, premature aging, diabetes, arthritis, etc., take health products rich in anthocyanins or Food becomes one of the most effective methods. At present, the raw materials for extracting anthocyanins at home and abroad are generally colored fruits such as purple grapes, blueberries, oranges, and raspberries, crop fruits such as purple sweet potatoes, colored flowers in plants, various colored vegetables such as purple radishes, red peppers, and tomatoes, etc. . But using these as raw materials has the following disadvantages: [0003] 1. The raw material planting and production...
