Research Abstract

This study aimed to investigate the tolerance to high soil temperature of sweet potato using twenty cultivars. They were evaluated at three levels of soil temperature under field condition. The coefficient of variation of commercial yield of tuberous root at three levels of soil temperature was used as the indicator of tolerance to high soil temperature. There were the varietal differences in the coefficient of variation. Soil temperature and the coefficient of variation of commercial yield decreased linearly with increasing canopy coverage in early growth stage. The translocation of assimilate to tuberous root decreased. These results suggested that the high canopy coverage in early growth stage was essential for stable tuberous root production under the high temperature.
