Abstract This study aims to determine the efficiency of water use between genotype and identify morphological characters of upland rice varieties tolerant to drought stress. The experiment was conducted in a plastic house in North Aceh, from January 2015 to May 2015. The study design was Split-Plot with three replications, by using two treatment factors, namely first factor is drought stress (C) consisting of 4 levels capacity airy namely: C1: 20%, C2: 40%, C3: 60% and C4: 80%. The second factor is the 10 varieties of upland rice varieties consists of 3 groups (the result of screening with PEG 6000), namely (tolerant varieties group) which consists of Ciapus, Inpago 4, Inpago 8. (Moderate varieties group) consisting of Inpago 5, Situ Bangendit, Inpago7, Towuti, and (susceptible varieties group) which consists of Inpari 6 JATE, Inpari 33 and Sintanur. Results of the study varied response of upland rice varieties in the group receiving the response of drought stress on the plant height, days to flowering, number of panicles and grain weight. Stress group 20% (C1) all varieties decreased plant height, number of panicles and grain weight as well as speed up flowering dates. Tolerant varieties are capable of producing that Inpago 4 and followed by Inpago 8. Groups of 40% field capacity (C2) tolerant varieties that adapt well to all the parameters are Inpago four varieties while the varieties best for moderate growth in the number of panicles and grain weight are mostly found in 60% of field capacity (C3) and the highest grain weight found in varieties Inpago 5. 80% field capacity (C4) group susceptible varieties are best found in Sintanur varieties. Keywords: Upland rice, varieties, water stress
