Study of Variation in Quantitative Traits of Poplar (Populus deltoides) Clones in Different Environments

The present study entitled “Study of variation in quantitative traits poplar (Populus deltoides) clones different environments” was undertaken the Department Tree Improvement and Genetic Resources, Dr. Y. S. P. U. H. F., Nauni- Solan 173230 (H.P.). three experimental sites namely 1) Dhaula Kuan, RH&TS, Dist. Sirmaur (H. P.), 2) Laddhowal farm, PAU, Ludhiana (Punjab) 3) Naganji nursery, Nauni, Solan. Variations significantly recorded at locations among all clones, such as leaf blade length, width leaf, midrib distance between petiole junction to base plant height, basal diameter stem volume higher values location follows by Kuan location. effect observed on also makes difference within same clone locations.
