Embodiment Construction

[0009] Black pearl waxy corn has a plant height of 170-190 cm, 12 leaves in the whole plant, white filaments and anthers, an ear height of 80 cm, and a high rate of double ears (the single ear of each plant is larger). In Hangjiahu area, it takes 85-90 days from sowing to picking fresh ears in spring, and 70-75 days from sowing to picking fresh ears in summer. The ear is thick, the grain is large and the skin is thin, leaving a single fruit, the ear length is 18-22 cm, and the ear diameter is 6 cm. The color is purple and black, the taste is sweet, and the quality is excellent. Strong and full without baldness, strong resistance to stress. Fresh ears can be harvested when the ear grains turn purple-black, and 1000 kg can be produced per 667 square meters. The row spacing between plants is 40×40 cm, and there are at most two plants in each hole.

[0010] The growth period of Fueryin waxy corn is 105-110 days, the harvest period of green food is 85-90 days, and the accumulate...

Abstract

The invention relates to a breeding method for fresh-eating red waxy hybrid maize belonging to the hybrid maize breeding field, comprising the procedures as follows: black pearl waxy corn with perfect plasmid and modena grain chosen as male parent and Darfur waxy corn with perfect plasmid and silvery white grain chosen as female parent are hybridized to establish an underlying group; recurrent selection is carried through in the underlying group in the aspects of red grain, waxy property, sweet taste, single plant production capacity, the ability of anti tan disease and lodging resistance, and repeated anisotropic hybridization and self-pollination are carried through to establish a hybridization group; the self-fertilization of parent strain and retrogression choiceness of the hybridization group are completed, vermeil hard grain is produced after 4-6 generations. The breeding method of the invention can breed the fresh-eating and eatable red waxy corn with high officinal value, good mouthfeel, high contents of natural haematochrome and rich nutrition which can be used in industry and as feed and has the advantages of strong ability to resist disease, drought resistance, flood resistance, high yield and fertility.

Description

technical field [0001] The invention relates to a waxy corn breeding method and belongs to the field of hybrid corn breeding. Background technique [0002] In recent years, the quality of life of our people has been continuously improved, and they are more and more particular about the taste and nutritional and health care value of food. In order to meet people's ever-growing demand for high-quality and diversified food, improve people's quality of life and eating habits, and enable agricultural production, especially land use efficiency, to develop stably, sustainably, and healthily, my country's agricultural production is adjusting its planting structure , the planting area of ​​special corn is increasing, especially sweet waxy corn. Due to the use of fresh fruit ears, the southern region can plant 2-4 seasons a year, and the economic benefits have been significantly improved. One mu of sweet waxy corn with a medium yield can be harvested in one season 750 kilograms of fres...
