The study was conducted to certify the differential tolerance response of selected rice cultivars, namely cv. Aichiasahi and Mushakdanti to oxyfluorfen, and cv. Chinsurah Boro 2 and IR 1846-284-1-1 to bensulfuron-methyl, in In vitro culture process. Isolated mesophyll single cells of the tolerant cultivar (Aichiasahi) were initially classified rather clearly in healthy cell number than in total cell number at concentration of 10** (-4)M oxyfluorfen. However, in case of bensulfuron-methyl there was no clear classification in susceptibility between the tolerant and the susceptible cultivars even at concentration of 10** (-3)M. Suspension cultured cells of the tolerant cultivar (Aichiasahi) were initially classified at concentration of 10** (-5)M oxyfluorfen in total cell number, but a shade of difference in survival rate was detected from the tolerant cultivar (Chinsurah Boro 2) at concentration of 10** (-3)M bensulfuron-methyl
