520			_aOpen-pollinated seeds are being used as supplementary genetic resources for Rubber Research Institute of Vietnam (RRIV) Hevea breeding program. These open-pollinated progenies over the years have shown good performance in small scale clone trials at different locations. In an attempt to enlarge genetic resources in Hevea breeding program, the open-pollination approach has been included in the RRIVs breeding programme since 2008. High rubber yield combined with the acceptable growth of open-pollinated progenies in both early selection trials and small scale clonal trials at different locations suggested that these progenies would be potential genetic materials for Hevea breeding. The high genetic variance and high coefficient of heritability for studied characteristics indicated that good hybrids could be produced from high yielding and vigorous parents through open-pollination. In summary, the study establishes the prospects of open-pollinated progenies in Hevea breeding program.
