A kind of breeding method of broad-resistant color wheat varieties

Abstract

The invention discloses a broadly-disease-resistant color wheat variety breeding method. The method includes: selecting a high-yield high-quality white-grain wheat variety as a recurrent parent, and taking black-grain wheat, purple-grain wheat, green-grain wheat, wheat scab resistance, full rot resistance and powdery mildew resistance varieties as character providing parents; performing hybridization, multiple crossing and multi-generation backcrossing to breed a near isogenic wheat line which is similar to the recurrent parent in plantleaf type, agronomical and yield characters and high in resistance and has characteristics of black grains, purple grains and green grains; proportionally mixing with the white-grain recurrent parent to obtain a broadly-disease-resistant color wheat production variety to realize production of color wheat containing wheat-grain wheat, black-grain wheat, purple-grain wheat and green-grain wheat. The broadly-disease-resistant color wheat variety breeding method is simple, efficient and feasible, and the produced color wheat is rich in various natural nutrient elements and physiological activators and is capable of improving health and regulating human circadian rhythm in frequency consumption. Since the selling price of the color wheat is high, income of planting of the color wheat variety is 500-600yuan higher than that of planting of a common variety per mu.

Description

technical field [0001] The invention specifically relates to a breeding method for wide-resistant color wheat varieties, and belongs to the technical field of disease-resistant special wheat breeding. Background technique [0002] Wheat is a monocotyledonous plant, a gramineous plant widely planted all over 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 successivel...

Problems solved by technology

[0005] 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
