Breeding method of new black glutinous maize variety

Abstract

The invention belongs to the technical field of maize breeding, and discloses a breeding method of a new black glutinous maize variety. The breeding method of the new black glutinous maize variety comprises the steps that parental breeding is performed, and hybrid breeding is performed; a green-stalk glutinous line is taken as a female parent and a black glutinous line 102 is taken as a male parent for crossbreeding, field yield, disease resistance, ear appearance and quality performance are judged, and a black glutinous maize hybrid is finally obtained and named Guiheinuo 609. The breeding method of the new black glutinous maize variety has the advantages that the yield is high and stable, the comprehensive disease resistance is high, the lodging resistance is good, the later green retention is long, the adaptability is wide, the firmness is good, bare tips do not exist, the ear appearance and quality are good, the grains are rich in melanin, glutinous and soft and has fragrance, maturity and sale are early, the method adapts to planting in sweet-waxy maize areas, and the new black glutinous maize variety is popular among consumers and has great market potential.

Description

technical field [0001] The invention belongs to the technical field of corn breeding, in particular to a method for breeding a new variety of black waxy corn. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Black glutinous corn is a special type of waxy corn. The cuticle of the grain has melanin deposited in different degrees, and the appearance is black and shiny. It is not only unique in color, but also rich in nutrition. Its seeds are rich in water-soluble melanin, trace elements needed by the human body, plant protein and various amino acids, and its nutritional content is significantly higher than that of other cereal crops. Black waxy corn pigment can effectively remove nitrite and block the synthesis of nitrosamines in the human body, which is an effective way to prevent cancer. The use of black waxy corn to develop functional health food has a promising prospect. At present, waxy corn variet...

AI Technical Summary

Problems solved by technology

[0005] (1) The planting area of ​​waxy corn in my country is about 10 million mu, and the variety of waxy corn required is increasing day by day, but it still cannot meet the market's demand for high-quality varieties with good comprehensive properties. Some waxy corn varieties are of low quality, single type, yield, and taste Poor, uneven processing quality

What is particularly outstanding is that the waxy corn varieties currently bred and sold on the market are mainly white-grained waxy corn varieties, and there are few special waxy corn varieties, which are difficult to meet the needs of agricultural industry upgrading, structural adjustment and market

[0006] (2) Narrow genetic basis of waxy maize germplasm resources is the main restrictive factor for breeding high-quality, high-yield and high-efficiency waxy maize varieties

At present, there is a lack of various types of high-quality germplasm resources and excellent waxy corn inbred lines, resulting in a single variety of waxy corn, and a lack of varieties with high yield, high quality, disease resistance, wide adaptability, and high added value.
