| Outline of Final Research Achievements |
Major climatic drivers of winter wheat yield were air temperature during grain-filling period in Tokachi region, and sunshine duration during grain-filling period in Okhotsk, Hokkaido. The regional difference in sensitivity of yield to air temperature is attributed to variations in sunshine duration during grain-filling period. This relationship between regional climate and crop yield analysis can demonstrate the mechanisms by which changes in regional climatic traits affect winter wheat yield. Field experiment used 'Kitahonami' and 'Yumechikara' as Tokachi and Okhotsk typical cultivars of winter wheat in Hokkaido, Japan. Natural stable isotope of carbon (delta 13-C) of leaf were relatively lower in 'Kitahonami' than 'Yumechikara'.
