A kind of breeding method of black glutinous rice

Abstract

The invention relates to a method for selectively breeding black glutinous rice. The method comprises the following detailed steps of: (1) hybridizing a black glutinous rice variety with a red glutinous rice variety to obtain an F1 generation, wherein all the seed husks of the F1 generation seeds are black; sowing the F1 generation to obtain an F2 generation; (2) sowing the F2 generation and separating a plant with black seed husks and a plant with white seed husks from the F2 generation; sowing plant seeds with excellent agronomic characters, deep black seed husks and glutinous endosperm; carrying out selfing for 6-8 generations to obtain the required variety. The rice bred by the method is good in glutinous property and excellent in growth vigour after being sown in large lands, the stems are thick and strong, the coarse rice is black, and the yield of the rice bred by the method is equivalent to that of the current high-yield white glutinous rice.

Description

technical field [0001] The invention relates to a method for breeding crops, in particular to a method for breeding glutinous rice with black seed coat. Background technique [0002] Black glutinous rice has a higher content of protein, mineral elements and vitamins than ordinary glutinous rice, especially the inorganic salts such as manganese, zinc, copper, calcium, phosphorus, potassium, magnesium, iron, and zinc contained in black glutinous rice are 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. Black 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 black glutinous rice are still the local varieties of the last century. The var...

Problems solved by technology

[0003] At present, the main varieties of black 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.
