| Abstract: | Restore line C470 was bred from Peiai 645×lunhui 422. Its grain aspect ratio is 3∶1, the leaf morphology inclined to indica rice. And the compatibility and rice quality inclined to aponica rice. Its chalky and chalkiness reached national best standards of a high-quality rice, both the advantage of breeding and quality significantly are increased. It can be used in production as japonica restorer lines or high-quality parent, and its disadvantage of restore range narrowness and poor cold tolerance are being improved. |
