On the cover

Canopy temperature is often related to the potential yield and is a possible yield indicator in crop breeding programs. The cover shows a typical example of the difference in canopy temperature between wheat cultivars ‘Kitahonami’ (high-yield, low-temperature) and ‘Hokushin’ (mid-yield, high-temperature). However, it is difficult to evaluate canopy temperature accurately in large-scale investigations, because canopy temperature is significantly affected by environmental conditions. In this issue, we have shown how environmental factors affect canopy temperature and have proposed a normalization approach for large-scale investigations (This issue, p. 520–527).
