Abstract

The yield of ten Hevea progenies derived from hand pollination in a set of 5 x 5 diallel crosses was analysed for combining ability. General combining ability variance (gca) and specific combining ability (sea) variances were highly significant. The gca : sca ratio was 1:2. Two parental clones, PR 107 and RRIM 628, were identified as general combiners with PR 107 being more suitable for the production of synthetic clones.
