The present study was carried out in the Laboratory and Field Experimentation Centre of Department of Biological sciences, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) during Rabi season 2021-22 and 2022-23, this experiment was conducted by randomized block design (RBD) design with six screening variety (V1-GP-170, V2-MGC-240, V3-MGC-222, V4-GP-87, V5-VL-191073 and V6-Check) and four treatment including control viz., T0-Control, T1PEG-11.8g\100ml water, T2PEG-19.7g\100ml water, T3PEG-25.4g\100ml water and T4 PEG-40.1g\100ml. It was found that significant difference between variety and treatment on Germination %, Germination rate, Seminal root number, Root length (cm), Shoot length (cm), Fresh weight (g), Dry weight (g) and Seed Vigour index, based on the research findings, it can be concluded that the six maize genotypes V5-VL-191073 and V3-MGC-222 performed better under drought conditions and thus can be declared drought tolerant, whereas the maize genotypes V1-GP-170 and V2-MGC-240 were regarded as drought sensitive when compared with other variety with To-control treatments.
