Evaluation of growth and yield for twelve selected hybrids from two recombination breeding programmes was conducted in a clonal nursery trial at Tripura (North East India). Girth, increment in girth and yield based on test tapping as well as under ethephon stimulation were evaluated. Based on mean girth and girth increment, 99/5/9, 99/3/61, 99/1/15 and 98/46 were identified as vigorous clones. Test tap yield in the peak season was highest for reference clone RRIM 600 followed by 98/46 Hybrid clones 99/5/9, 99/3/61 and 99/5/35 also had test tap yield above the grand mean in both peak season and summer season. Assessment of intra-clonal variability through boxplot analysis revealed that among the promising clones 98/46, 99/3/61 and 99/5/9 had a lower range in girth, while 98/46 and 99/5/9 had better uniformity in yield. Significant yield-girth correlation was observed within clones in the second year of test tapping. Hybrid clones were classified based on mean and proportion of trees in the above average category. Clones 99/3/61, 99/5/9 and 98/46, belonging to the high girth and high yield categories, recorded higher mean yield than the grand mean over three years of test tapping, were comparable with RRIM 600 and identified as potential clones for further evaluation.
