Abstract
The study was conducted in Himachal Pradesh to estimate the variability for the phenotypic characters of Toona ciliata among the altitudinal provenances and zones. The characters like leaf length, number of leaflets per leaf, inflorescence length, number of flowers per inflorescence and crown spread differ significantly for altitude and zones. Wide range of genetic variabilities were observed for almost all the characters. The characters leaf length/inflorescence length in case of altitudinal provenances and number of flowers per inflorescence, crown area in zones had high estimate of genotypic co-efficient of variability, heritability and genetic advance which indicated importance of these characters for selection.
