N2  - The growth and yield performance of three natural rubber (Hevea brasiliensis) clones were evaluated in dry sub- humid climate in Odisha in eastern India. In this region, crop experiences severe drought in summer months. Prolonged high summer temperature and soil moisture stress are the major environment constraints. Analysis of growth performance of the clones revealed that GT1 had the highest girth and girth increment. Clone RRII 105 (32.8g t-1 t-1) had superior yield contribution for all three clones was recorded in winter season. More incidence of tapping panel dryness was noticed in RRIM 600. Wind damage was the highest in RRII 105. Comparatively higher timper bole volume was estimated in clone GT1 (0.09m3 per three). Growth, yied and other secondary characters of three popular Hevea clones in the drought prone region are discussed
