Frequency distribution of canopy temperature differences (CTds) in two reciprocal populations crossed between ‘Koshihikari’ and ‘Takanari’. Black and white arrows indicate CTds in ‘Takanari’ and ‘Koshihikari’, respectively. The reference variety was ‘Koshihikari’ in BKT or ‘Takanari’ in BTK for the calculation of CTds as described in Materials and Methods. The weather conditions at the measurements were shown in Supplemental Fig. 2.
