ESTIMATES OF GENETIC PARAMETERS FROM AN OPEN POLLINATED GENETIC TEST OF TEAK (<em>TECTONA</em> <em>GRANDIS</em>)

Abstract

Genetic parameters were estimated from a 7-y-old open pollinated progeny test of teak. The results indicated presence of significant amount of genetic variation in the materials studied. Height, diameter and basal area were found to be under the control of additive gene action as evidenced by their moderately high values of individual tree heritability. The genetic gain values followed a similar trend. Basal area and diameter exhibited positive significant genetic correlation. Clones ORANP-1 and ORANP-5 were found to be the best general combiners for height, diameter and basal area.
