Abstract
Fifteen clones were planted during January 2000 in nursery area of the Department of Forestry, CCS Haryana Agricultural University, Hisar, in randomized block design with three replications. Analysis of variance indicated presence of variation for basal girth, shoot length, fresh shoot weight, dry shoot weight, root length, root spread, fresh root weight, dry root weight, root length: shoot length ratio and root weight: shoot weight ratio in fifteen clones of Populus deltoides under nursery conditions. Little difference between genotype coefficient of variation and phenotypic coefficient of variation and medium to high estimates of heritability for all the characters under study revealed the heritable nature of variability present. Estimates of genotypic advance as percentage of mean were observed high for all the characters under study. The clones viz., 146 and 154 of M/s WIMCO Seedlings Ltd., were observed as best clones and the clones viz., 28, 156, 139 were considered as potential clones.
