Since rice is highly susceptible to water stress, it is important to improve drought resistance to increase and stabilize the rice yield under upland cultivation conditions. This study was conducted during 1995 in Utsunomiya, Japan to elucidate the morphological and physiological characteristics related to drought resistance in diverse rice germplasm. Six cultivars including japonica, indica and japonica-indica hybrid cultivars were grown in a pot with the same soil water deficit conditions at the vegetative growth stage.
