Twenty potato genotypes were assessed for water stress sensitivity during 2009 and 2010 at Horticulture Research Farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur, Bangladesh. The experiment was carried out in completely randomized design (CRD) comprising two factors with four replications. Selection of the genotypes for water stress condition was done following different stress tolerance attributes likes; relative performances, stress susceptibility index, tolerance and stress tolerance index. Local cultivars Indurkani, Shilbilati and Sadaguti showed high degree of tolerance to water stress with low productivity in both conditions. CIP genotype CIP 396244.12 had the highest yield under water stress condition followed by CIP 393371.58. Under water stress condition, as genotype with higher yield is desirable. So, considering yields and different stress attributes, CIP genotypes CIP 396244.12 and CIP 393371.58 were found suitable for water stress condition.
