Breeding method for edible high-quality ion-zinc-rich rice

Abstract

The invention discloses a breeding method for edible high-quality ion-zinc-rich rice. The breeding method comprises the following steps: selecting red rice variety as a parent A, selecting zinc-rich rice variety as a parent B, and selecting glutinous rice variety as a parent C, using the parent A as the female parent, using the parent B as the male parent, hybridizing, and obtaining the first generation F1 of A / B; using the F1 as the female parent, using the parent C as the male parent, hybridizing, and obtaining the first generation F1 of A / B / / C; selfing the F1, and obtaining the second generation F2; selfing the F2, performing the planting and harvesting according to the single plant, successively using the red rice, the glutinous property and the zinc-rich as the sieving indexes, and obtaining the third generation F3; performing the inbreeding of more generation to the F3, and obtaining the homozygous later generation with the red rice, glutinous property and zinc-rich characters; performing the inbreeding of more generation to the homozygous later generation, and obtaining the later generation with good agronomic characters; and performing the inbreeding of more generation to the later generation, breeding a strain with stable character, and obtaining the edible high-quality ion-zinc-rich rice. The cultivated rice variety belongs to the red rice variety, is edible in high quality and contains iron and zinc richly.

Description

technical field [0001] The invention relates to the technical field of rice breeding, in particular to a breeding method for edible high-quality iron-zinc-rich rice. Background technique [0002] Red rice has been cultivated in my country for thousands of years. Traditional Chinese medicine believes that red rice can nourish yin and nourish the kidney, invigorate the spleen and whet the appetite, and is a health food for delaying aging. According to testing, red rice is rich in protein, amino acid, unsaturated fatty acid and various vitamins necessary for human body, and also contains many special nutrients such as iron, selenium, organic germanium, etc.; at the same time, red rice also contains active ingredients such as flavonoids. Unfortunately, red rice is generally of poor eating quality. [0003] Zinc is an important micronutrient element necessary for the human body. It is not only related to the synthesis of human life substances (nucleic acid and protein), but als...
