Abstract

The present study was carried out to estimate the genetic variability, heritability and genetic advance in various clones of Eucalyptus tereticornis. The estimates of phenotypic and genotypic coefficients of variation clearly reflected the presence of large amount of genetic variability for clearbole height and unforked height, and reasonable amount of genetic variability for total height and diameter at breast height. Heritability estimates (in broad sense) reflected the predominance of heritable variation for all the characters under study. The estimates of genetic advance as percentage of mean clearly suggested the potentiality of the clonal material for improvement of total height, diameter, clearbole height and unforked height through selection. Significant positive correlation was observed among clearbole height and unforked height indicating the positive association of these characters with each other.
