Abstract
Soybean (Glycine max (L.) Merr.) is the most important crop as a major source of protein and oil for humans and farm animals. A further increase in soybean yield is required to meet the food demand from the rapidly growing human population. This chapter discusses the great potential of genetic diversity in leaf photosynthesis to lead toward soybean yield improvement by utilizing a molecular breeding approach. Previous studies have discovered considerable variations in the photosynthetic rate under steady and non-steady state among the field-grown soybeans. These genotypic variations are attributed to diversities in gas diffusional and biochemical traits, especially stomata and Rubisco-related characteristics. In addition, genetic studies have identified the quantitative trait locus affecting genotypic variations in the steady-state photosynthetic rate among soybeans. The low efficiency of photosynthetic measurements has been a major bottleneck slowing down genetic studies in the field-grown crops. Therefore, enhancement of phenotyping efficiency can accelerate the understanding of genetic mechanisms regulating the diversity in leaf photosynthesis, which would contribute to further yield improvement through future soybean breeding.
