Breeding method of two-line selenium-enriched three-color formula fragrant rice hybrid rice variety

Abstract

The invention discloses a breeding method of a two-line selenium-enriched three-color formula fragrant rice hybrid rice variety, and belongs to the breeding technical field of special rice. According to the method provided by the invention, a selenium-enriched green rice variety and a selenium-enriched giant embryo rice variety are hybridized to cultivate fragrant green giant embryo rice variety through selection of characters of multiple generations. A fragrant two-line sterile line and yellow rice are hybridized to cultivate a fragrant yellow rice two-line sterile line through the selection of the characters of the multiple generations. The fragrant yellow rice two-line sterile line and the selenium-enriched fragrant green giant embryo rice are hybridized to cultivate hybrid F1-generation seeds, namely, fragrant yellow and green giant embryo hybrid F1. After the F1 is planted, selenium-enriched fragrant rice with different colors and types can be produced by using harvested rice after being subjected to roughness removal. According to the breeding method, the two-line selenium-enriched three-color formula fragrant rice hybrid rice variety is bred, the production method is simple, high in efficiency and good in effect. The produced functional selenium-enriched three-color formula fragrant rice can integrate fragrance, color, taste and nutritional curative effects. Nutritional ingredients such as selenium element, gamma-aminobutyric acid and various mineral substances can be effectively supplemented for a user after being eaten for a long time so as to promote the human health.

Description

technical field [0001] The invention specifically relates to a method for breeding a two-line selenium-enriched three-color formula aromatic rice hybrid rice variety, which belongs to the field of special rice breeding. Background technique [0002] In recent years, with the intensification of environmental pollution and significant changes in people's lifestyles and dietary patterns, the nutritional imbalance of mineral elements has become an important factor affecting human health. Selenium is an essential trace element for human growth and development. It is of great significance to prevent and treat diseases and prevent aging. It is praised by scientists as the "king of anti-cancer and anti-cancer". A variety of diseases such as selenium have unique preventive and therapeutic effects, and proper selenium intake can also promote growth, protect vision, delay aging, and have the effect of resisting AIDS. Two-thirds of China's population is deficient in selenium to varying...

Problems solved by technology

The current method of making formula rice in the market is to plant different types of rice separately and then mix them mechanically. It is mainly made by mixing black rice, glutinous rice, and red rice in proportion. This method has cumbersome procedures and high production costs.

At present, there are no reports at home and abroad that can produce selenium-enriched green rice, yellow rice, white rice, and formula rice varieties and breeding methods combined with giant embryos and fragrance.
