Embodiment 1

[0023] (2) Field identification was carried out in Kunming, Yunnan in 2005. Cainuo 3 had an average yield of 986.5 kg of fresh fruit ears with bracts per mu, which was 25.5% higher than that of the control Yu Nuo 7; Yunuo 7 increased yield by 22.0%; the plants are neat and tidy, the plant type is scattered, and the leaf sheaths are green; it can be marketed after 90 days of summer sowing in Kunming; the average plant height is 265 cm, the ear height is 85 cm, the ear length is 18.5 cm, and the ear diameter is 5.0 cm. The number of ear rows is 14-16, the number of rows of grains is 36, and the weight of 100 fresh kernels is 45 grams; the bract leaves are well covered, and the ears are columnar. When harvested, the kernels of the same ear have five colors: white, red, gray, purple, and black. Neat, good appearance quality, thin peel, good waxiness, good eating quality.

Abstract

The invention discloses a method for breeding hybrid seeds of color waxy corn and belongs to the technical field of crop seed breeding. In the method, a white waxy corn self-bred line is used as a female parent, a black waxy corn self-bred line is used as a male parent, and hybrid seeds of color waxy corn can be bred by hybridization. The method can breed hybrid seeds of color waxy corn which can grow three-color ears by hybridizing the white waxy corn self-bred line and the black waxy corn self-bred line. The breeding method is smart, simple, convenient and quick; the bred hybrid seeds of color waxy corn have high yield and quality, 986 kilograms of fresh ears with bracts can be produced in each mu, and the yield is increased by 26 percent compared with reference Yunuo No.7; the average yield of fresh ears without bracts per mu is 785 kilograms, and the yield is increased by 22 percent compared with that of Yunuo No.7; the fruit skin is thin, the taste and waxy property of the fruit are excellent, the content of branch starch is 19.77 percent and accounts for 98.28 percent of coarse starch; and the straight-chain starch accounts for 1.72 percent of coarse starch and the bred hybrid seeds reach national grade 2 quality standards for waxy corn.

Description

[0001] technical field [0002] The invention belongs to the technical field of crop breeding, and in particular relates to a breeding method for a colored waxy corn hybrid. Background technique [0003] Waxy corn, also known as waxy corn or sticky corn, is a new type of corn that is mutated from common corn and then artificially selected. It is affected by a single recessive gene wx Control, grain endosperm starch is all amylopectin. Compared with ordinary corn, waxy corn has higher nutritional value, economic value and processing value. Its protein content is 3-6% higher than ordinary corn, and its lysine content is 16-74% higher than ordinary corn. It is also rich in corn. Amino acid, alanine, tryptophan, multivitamins and trace elements and other nutrients, the digestibility is 16% higher than that of ordinary corn, the grains are sticky and soft after steaming fresh food, the fragrance is sweet, the skin is thin and dregs-free, and the taste is soft It is slippery and...
