Research on super rice physiological breeding progress

A introduction to the researching progress in terms of radication vigor of super rice and its influential facts, photosynthesis mechanism, its yielding process, and of stems'' transforming and accommodating mechanism. A notion is brought forward that the researches on the super rice physiological breeding and the interconnections between its related physiological characters in physiological process on cell''s level and objective characters on morpha level must be strengthened. Physiological foundations must be established on molecular level in order to realize high output of rice. On the basis of the interdependent relations on different physiological levels from molecules to colonies, by utilizing bioinformatical researching approaches, computer simulation method, digitalized physiological breeding process can be achieved gradually.
