520			_aA study was carried out to determine the clone X environment interaction during the early growth phase of 15 Hevea clones at Taranagar Farm of the Regional Research Station of the Rubber Research Institute of India. The results showed that the rate of increment in girth significantly decreased with increasing age irrespective of seasons (winter/summer). However, there was wide differences between the girth increment during summer and winter months. GE interaction parameters like ecovalence and stability variance showed that clones studied have differential adaptability. The data suggest that clones RRIM 600, PB 86 and GT 1 are widely adapted showing more flexibility and those like RRII 105 are specifically adapted with less flexibility. The results indicate that selection for phenotypic stability can lead to isolation of stress resistant genotypes.
