1 R&D FOR RUBBER INDUSTRY IN VIETNAM PHAN THÀNH DŨNG Rubber Research Institute of Vietnam Panel 3 : Current challenges in research for smallholder rubber plantations

2 INTRODUCTION  Rubber tree (Hevea brasiliensis Mull.-Arg) was introduced into Vietnam by Dr. Yersin, French scientific, and has been commercially since 1906 in Southeast Region.  By 1976, rubber area was ha only produced ton (0,52 ton/ha). In  By 1976, rubber area was ha only produced ton (0,52 ton/ha). In 2007, total rubber area accounted upto ha and gave the production tons (1,612 ton/ha)

3 Introduction of rubber tree into Vietnam Wickham collected rubber seeds rubber seeds germinated Kew Gardens (England) 3. Rubber seeds arrived to Ceylon seedlings transferred to Singapore , Rubber tree introduced into Vietnam.
