dc.description.abstractABSTRACT The present investigation entitled “Nursery evaluation of Populus deltoides Bartr. hybrid clones” was carried out in the Department of Tree Improvement and Genetic Resources, Dr YS Parmar University of Horticulture & Forestry Nauni, Solan (HP) during 2016-2018. The twenty hybrid clones developed by UHF, Nauni, and two controls were planted at a spacing of 60 X 60 cm in randomized block design (RBD) with three replications and were evaluated for morphometric characters at nursery stage. Analysis of variance revealed significant differences among clones for all the traits. On the basis of mean values of growth characteristics, some best performing clones were identified viz. Kranti X 39N (17-5), S1 X S7C11 (11-4), S1 X 17/92 (9-4), S1 X S7C4 (5-3) etc. and field testing is suggested for these clones. Quantitative leaf characteristics were also evaluated as determinants of productivity. Qualitative descriptors were prepared for poplar clones based on leaf, stem and branch characters. Estimation of genetic components was carried out which revealed high heritability and high genetic gain in plant height, collar diameter, bud length and leaf area. All growth traits were positively correlated with each other as well as with most of the leaf traits. On the basis of clustering, twenty-two clones were distributed in three clusters suggesting inter-cluster crossing would be effective in future breeding programs.en_US
