A kind of breeding method of red glutinous rice

Abstract

The invention relates to a method for breeding red glutinous rice, comprising the following specific steps: (1) hybridizing black glutinous rice with red sticky rice varieties to obtain single-cross F 0 , planted single-cross F 1 (2) Using the high-yield Bainuo variety Gui D1 as the female parent, the single-cross F 1 F 0 generation; (3) planting and recrossing F 0 Harvest F 1 Generation, F 1 The seed coats of the substitutes were all black; planting F 1 Generation Harvest F 2 Generation, F 2 Black, red and white seed coats are separated from the first generation, and the seeds of the plants with red seed coats and waxy endosperm are selected for planting; after 6-8 generations of selfing, the desired red glutinous rice variety is obtained. The rice cultivated by the invention has good waxy property, good growth when planted in the field, strong stem, red brown rice, and the output is equivalent to the current high-yield white waxy rice.

Description

technical field [0001] The invention relates to a method for breeding crops, in particular to a method for breeding glutinous rice with red seed coat. Background technique [0002] Red glutinous rice has a higher content of protein, mineral elements and vitamins than ordinary glutinous rice, especially red glutinous rice contains manganese, zinc, copper, calcium, phosphorus, potassium, magnesium, iron, zinc and other inorganic salts are mostly higher than ordinary rice 1- 3 times, it also contains special ingredients such as vitamin C, chlorophyll, anthocyanin, β-carotene and cardiac glycosides that ordinary rice lacks, so it is more nutritious than ordinary glutinous rice, and has good diet and health effects. Red glutinous rice pigment is also a natural pigment, non-toxic, and maintains a variety of nutrients rich in plants, and can be used as a food coloring agent. [0003] At present, the main varieties of red glutinous rice are still the local varieties of the last cen...

AI Technical Summary

Problems solved by technology

[0003] At present, the main varieties of red glutinous rice are still the local varieties of the last century. The varieties are seriously degraded, the yield is low, the benefit is low, and the planting area is decreasing year by year, resulting in a shortage of supply in the market.
