| Outline of Final Research Achievements |
The leaf photosynthesis is one of the most important trait to determine the soybean productivity. This study elucidated that a local variety, PI603911C, showed the extremely high photosynthetic rate under the ambient and high CO2 condition. This phenotype is partly attributed to the greater carboxylation activity in the mesophyll cells. This study also detected several soybean varieties having high photosynthetic rate. Notably, these varieties achieved high photosynthetic rate with different physiological mechanisms. It is expected that this study provides useful information to the future soybean breeding programs.
