Breeding method of three-line hybrid combination of colored rice

Abstract

The invention discloses a breeding method of three-line hybrid combination of colored rice. The method comprises the following steps: carrying out hybridization and backcross by taking colored rice Cas a male parent and a three-line maintainer line B as a female parent, and breeding a three-line maintainer line and a three-line sterile line of colored rice; carrying out hybridization and backcross by taking colored rice D as a male parent and a restorer line R as a female parent, and breeding a colored rice restorer line; screening heterosis, and screening based on rice quality, yield and resistance to obtain a new colored rice three-line hybrid combination; and finally, constructing a three-line hybrid system of colored rice. The method provides a natural five-color colored rice three-line hybrid rice, the rice is obviously different from conventional single-color colored rice conventional varieties or hybrid varieties produced at present, and changes a current situation that the so-called five-color rice is formed by mixing various colored rice in the market; and the rice has more complete nutrition and more uniform quality, and is beneficial to cooking and deep-processing applications.
