Owing to their specific photoperiodic requirements, different exotic genotypes of Populus were introduced in Terai region of Uttar Pradesh. The indigenous clones were also developed from open pollinated seeds. Their screening was conducted in nursery to select promising ones which were further studied in populetums. Afterwards they were evaluated in field. Overall performance of indigenous and American clones was found better than those obtamed form other sources. Some of the outstanding clones were S7C15, S7C20, G-48, 1–18/62, L-34, L-52, EL-74, S7Cl, D-75, L-51/84, L-154/84, L-301/84 etc.
