บทคัดย่อ (EN): As non-traditional rubber growing regions, the Northern part of Vietnam presents various stress factors, particularly climate features such as prolong low temperature and low solar radiation in the winter, very high air temperature in the summer, strong wind etc. Acclimatization of rubber trees to non-traditional region has gained the attention of the rubber plantation industry and policy makers to meet the increasing demand foe natural rubber. In this context, evolving planting material for cultivation rubber trees in such area is one of the mandates of research. Experiments were conducted in the Northern part of Vietnam, located between 19O19N (Nghe An) and 22๐33N (Lai Chau), involving several Hevea clones, of which the majority are RRIV’s clones. These clones have been evaluated for their adaptabilities and performances in the cold climate. As the results in SSCT in Nghe An and Phu Tho provinces show, many RRIV’s clones have not only showed a good adaptability to cold climate but also good yield performances in comparison with the recommended clones, RRIM 600 and GT 1. Among them, RRIV 104 and RRIV 104 have been considered as the most promising clones in these areas. In addition, various LSCT and Block planting trials have been also conducted in the northern mountainous region since 2008 with a large number of RRIV’s clones. At the immature period, low temperature showed to affect the growth of these clones, however, the severity of influence varied among clones. The results indicated that the performance of the clone RRIV 124 was not only the most stable in all clonal trials but also in large planting areas due to its cold tolerance and recovery after serious cold-waves. The other promising RRIV”s clones were RRIV 210 and RRIV 125.
