<p>Teak (<i>Tectona grandis</i>) is an economically important timber species, and India has a large distribution of natural teak forests. The present investigation assesses a more than 30-year-old clonal trial containing ramets from different parts of India, established at the Tropical Forest Research Institute, for growth traits and qualitative characteristics (straightness of bole, crown compactness, forking, tree health, and flowering). A linear mixed model (LMM) with clones as fixed effects and replication as random effects was fit for quantitative traits in the study, and restricted maximum likelihood (REML) was used for estimation of variance components. Estimated marginal means (EMMs) for clones were calculated, and Sidak’s post hoc test was applied for comparison between clones. The clones had significant variations in growth traits, viz., clear bole height, girth at breast height, height, and wood volume. All the growth traits had significant associations with each other. Hierarchical clustering grouped the clones into 5 different clusters. The clones, viz., APNPL-4, KLK-1, ST-16, and MHALP-1, performed better for growth traits and were grouped into cluster V. The clones of cluster IV, viz., ORPDP-29, and MYSA-2 had lower values for growth traits and one or more qualitative traits and thus, could be rogued out of the trial to realise increased genetic gain in progeny. The clone KLK-1 had high estimated marginal means for all the growth traits and showed desirable values for all qualitative traits except flowering. The nearness of the test site to the place of origin of clones was observed to be inconsequential for growth traits in the study.</p>
