บทคัดย่อ (EN): North Konkan region of west coast of India is conditionally suitable for rubber (Hevea brasiliensis) cultivation. The region experiences prolonged sever soil moisture deficit (5-6 month per year), high temperature (occasionally goes to 41°C), high intensities of the solar radiation (11 hrs), very low atmospheric humidity (36%) and annual rainfall ranging from 2300 – 2800 mm (June-September) with non satisfactory contribution due to its unimodal pattern. A study was undertaken at Regional Research station. Dapchari (20.04° N altitude and 72.01° E longitude with 48 MSL) to evaluate the growth and initial yield performance of three primary clones (Ortat selection) and twelve secondary clones (derived from known parentage) evolved in India (RRII 5, RRII6, RRII 105, RRII 208, RRII 308), Indonesia (PR 255, PR 261), Malaysia (RRIC 52, RRI 100, RRII 102< RRII 105) under prevailing condition of dry sub humid North Konkan region of western India. The observations on girth (cm) at, immature, mature phase, MGI (mean girth increment, cm per year) in immature phase and seasonal yield (gram per tree per tapping) i.e., annual yield, peak yield, stress yield and % summer yield depression for four years after tapping found highly significant, No difference in variability were recorded for the characters i.e., juvenile girth and mature MGI. The clone RRII 105 performed better in respect of vigor and yield followed by RRII 208, RRII 6, PR 255, and RRIC 100 in initial two years of tapping. Clone RRII 208 attained a highest yield from third year after tapping. The less summer yield reduction was also noticed in higher yielder clones while maintaining high summer yield which indicates, the ability of these clones to withstand in severe drought condition of North Konkan region. Better initial survival, early tappability, wide adoptability to initial growth, higher yield, stability, better yield during annual, peak yielding andstress seasonof clone RRII 208, RRII 105, RRII 6 indicates their potentiality for as a parents for improving breeding and selection work and for future planting in this drought prone region.
