Varieties differed significantly in maximum root length at 45 DAS [days after seeding], root dry weight, shoot length, leaf dry weight, leaf area, leaf water potential, and SES scores. Salumpikit (resistant check) and IR 47686-1-4B showed the greatest drought tolerance, IR20 and ARC 7098 the least. All growth, physiological, and standard evaluation system for rice (SES) parameters except shoot length were significantly (P 0.05) correlated with one another. The most efficient parameters for dividing genotypes into the greatest number of classes was leaf water potential. Average SES scores of susceptible and resistant checks from this pot screening were significantly correlated with average scores from field drought tolerance trial results in the IRRI [International Rice Research Inst., Los Banos, Laguna, Philippines] data bank (r
