Abstract

Wood density variation was studied in 14 years old teak clones and in 59 years old provenances grown in Kerala. Analysis of the data showed that phenotypic coefficient was low for both clones and provenances and genotypic coefficient variation was negligible. The heritability on individual tree basis was low for clones while it was zero for provenances. Wood density showed a weak phenotypic correlation and a negative geneotypic correlation with girth at breast height. Whatever variation is existing, the major part is due to tree-to-tree variation rather than provenances and hence selection of individual trees will help the improvement programme
