Selective breeding technique of anthocyanin type purple corn

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...

AI Technical Summary

Problems solved by technology

[0003] 1. The raw material planting and production areas are limited by geographical conditions and climate, and the cultivation technology requirements are relatively strict;

[0004] 2. It is inconvenient to pick, store and transport, and requires stricter conditions;

[0005] 3. The output of raw materials is low and the production cost is high;

[0006] 4. Its efficacy is not as good as purple corn anthocyanins
