Evaluation of genotypic variation in leaf photosynthetic rate and its associated factors by using rice diversity research set of germplasm. Abstract Text:
In order to evaluate genotypic variation, we measured leaf photosynthetic rate (Pn) and its associated factors for the rice diversity research set of germplasm (RDRS) selected from the Genebank in National Institute of Agrobiological Sciences (NIAS). Pn showed large genotypic variation from 11.9 to 32.1 micromol m(-2 )s(-1). The variation in stomatal conductance to CO2 (Gs) explained about 50% of that in Pn, while that in nitrogen concentration (N) in leaves explained about 35%. The genotype group which mainly consists of aus type indica tended to have higher Gs, and the genotype group which corresponds to japonica had a higher nitrogen concentration (N) in leaves. The relationships of Pn with Gs and N were not significantly different among genotype groups, suggesting photosynthetic efficiencies are similar among genotype groups.
