Problems solved by technology

[0004] At present, there are few colored wheat varieties in my country, only some single-color wheat varieties, and only some "color formula wheat" mixed with different colors of wheat are sold in the domestic and foreign markets. The production method is to plant different color types of wheat separately. Production, and then mechanically mixed in proportion, this method is quite cumbersome and the production cost is high

Embodiment 1

[0023] A kind of breeding method of colored wheat variety, concrete steps are:

[0024] 1) The high-yield and high-quality white-grained wheat variety Ningchun 16 (parent R) was selected as the recurrent parent, and it was mixed with the black-grained wheat variety (P1) Luozhen 1, the purple-grained wheat variety (P2) Shannongzimai 1, and the green wheat variety (P2). The grain wheat variety (P3) Zhongpulumai No. 1 was crossed, in which R was used as the female parent, P1, P2, and P3 were used as the male parents, and the hybrid F 1 F 1 -1, F 1 -2, F 1 -3 means;

[0025] 2) Planting hybrid F 1 Generation Seed F 1 -1, F 1 -2, F 1 -3 each with 10 plants, 2 excellent individual plants were selected from each at the flowering stage and backcrossed with the recurrent parent R (as the female parent) respectively to obtain the first generation of backcrossed BC 1 f 1 -1, BC 1 f 1 -2, BC 1 f 1 -3;

[0026] 3) Planting backcross 1 generation BC 1 f 1 -1, BC 1 f 1 -2, BC...

Abstract

The invention discloses a method for breeding a color wheat variety and belongs to the technical field of special wheat breeding. According to the method, a white-grain wheat variety with high yield and high quality is selected to serve as a recurrent parent and hybridized with black-grain wheat, purple-grain wheat and green-grain wheat, progeny and the recurrent parent are subjected to multi-generation backcross, a wheat near-isogenic line is bred and mixed with the white-grain wheat recurrent parent in certain ratio, and a color wheat production variety is generated, wherein for the wheat near-isogenic line, plant and leaf types, agronomic characters and yield traits of the wheat near-isogenic line are close to those of the recurrent parent, and the wheat near-isogenic line has characters of the black grains, purple grains and green grains. After the color wheat variety is planted, the plant and leaf types and the agronomic characters are neat and the same, the yield is high, and harvested wheat contains white-grain wheat, black-grain wheat, purple-grain wheat and green-grain wheat, integrates color, aroma, taste and nutrition efficacy and has very good nutrition and health care functions.

Description

technical field [0001] The invention specifically relates to a breeding method for colored wheat varieties, and belongs to the technical field of special wheat breeding. Background technique [0002] Wheat is a monocotyledonous, grassy plant that is widely grown around the world. Wheat is one of the three major grains, almost all of it is used for food, and only about one-sixth is used as feed. After being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods; after fermentation, it can be made into beer, alcohol, and liquor . Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin, vitamin A and vitamin C, etc. [0003] Colored wheat is a new variety of high-quality wheat bred by different breeding methods. Because the seed coat or aleurone layer is rich in natural anthocyanins, the grains appear black, purple, blue, green, etc. Chinese scholars successively cultivated a series of high-qualit...
