Influence of polyethylene glycol (PEG) mediated osmotic stress on reactive oxygen species (ROS) scavenging machinery of Chinese potato ( Solenostemon rotundifolius  (Poir.) J. K. Morton) was investigated. Five genotypes of Chinese potato were raised in Murashige and Skoog (MS) basal medium containing 6–benzylaminopurine (BAP, 1 mg L –1 ) along with various concentrations of PEG–6000 mediated stress conditions (0, –0.2 and –0.5 MPa) and evaluated for osmotic stress tolerance  in vitro . The medium containing PEG–6000 had a detrimental effect on plantlet growth and development while compared with the control. Accumulation of H 2 O 2  was lower in Sreedhara and Subala and higher in Nidhi under PEG stress, which was evident by  in situ  detection in leaves. Lipid peroxidation product such as malondialdehyde (MDA) content was increased due to PEG stress which was more in susceptible genotype than that in tolerant ones. An enhanced ROS–scavenging antioxidant enzyme was observed under stress with respect to the control. The enzymes of ascorbate–glutathione cycle showed an important role in scavenging ROS. The imposition of PEG stress also increased the non–enzymatic antioxidants  viz ., the ascorbate and reduced glutathione content which was prominent in tolerant genotypes in comparison to susceptible. The present study indicated that, Sreedhara and Subala showed more tolerance to osmotic stress with better ROS scavenging machineries which would be the lines of interest for augmenting future breeding strategies in this climate resilient minor tuber crop.
