Embodiment Construction

[0010] 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 40x40 cm, and there are at most two plants in each hole.

[0011] 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 belongs to the field of hybrid corn breeding and relates to a breeding technology of bright red selfing superhigh-yield corns. The breeding technology comprises the following steps: by selecting black pearl waxy corns with full plasmids and dark violet particles as father parents and selecting Fueryin glutinous corns with full plasmids and argenteous particles as mother parents, hybridizing and establishing a base population; carrying out recurrent selection on redness, waxiness and sweetness property of the particles as well as the production capacity of single plant, brown blotch resistance and lodging-resistance capability by adopting the base population, carrying out repeated incongruous hybridization and self-pollination, and establishing a hybrid population; and carrying out parent selfing and degeneration selection by using the hybrid population, and producing bright red hard particles after 4-6 generations. According to the breeding technology, the fresh, edible, industrial and feedable red waxy corns which have the advantages of high phamaceutical value, good fresh mouthfeel, rich nutrients, strong disease resistance, drought resistance, waterlogging resistance and high yield and contain high-content natural red pigments can be cultivated.

Description

technical field [0001] The invention relates to a breeding technology of bright red self-crossing super high-yielding corn, which 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 getting bigger and bigger, especially sweet waxy corn. Due to the use of fresh ears, southern regions can plant 2 to 4 seasons a year. 750 kilograms of fresh ears, the net income is about 1,000 yuan, which is 4 times higher than that ...
