Clonal Evaluation of Poplar (Populus deltoides Bartr.) in Eastern Uttar Pradesh. I - Nursery Testing

75 different clones of Populus deltoides were screened in nursery stage under Eastern Indo-Gangetic conditions for recommending suitable clones for large-scale plantation in different Agro-forestry systems. Four commercial clones namely G3, G48, D121 and Udai were treated as check and these were compared with the rest of the clones. Eleven best clones (D121, D124,82-26-5, 34-N, 40-N, 25-N, UD-36, UD-5502, 90-12, UD-6502 and UD-4707) are earmarked on the basis of independent culling methods of selection. Another set of 12 clones were closely followed to the first set of 11 best clones are also graded as potential clones. The field trials of promising clones have already been undertaken for selecting the site matched clones for commercial culture of Poplar in Eastern parts of Uttar Pradesh.
