Putative QTLs controlling the leaf photosynthetic rate detected in the BC5F2 populations grown in the paddy field at the full heading stage
| Trait | Chromosome | Flanking marker | LODa | Ab | Dc | R2d |
| Photosynthetic rate | 4 | RM3836 | 2.4 | 1.3 | 0.0 | 9.1 |
| 8 | RM6999 | 5.1 | 1.7 | 0.0 | 6.2 |
The QTLs on chromosome 4 and 8 were detected in the 611-8 F2 and 611-10 F2 populations, respectively. The photosynthetic rate was measured with an LI-6200 system at an ambient CO2 concentration of 370 μl l−1 between 08:30 and 11:00.
a
A putative QTL with significant LOD scores in 1000 permutation tests at the 5% level.
b
Additive effect of the allele from Habataki compared with that from Koshihikari.
c
Dominant effect of the allele from Habataki compared with that from Koshihikari.
d
Percentage phenotypic variance explained by each QTL.
