Mini-seedling budding of Hevea brasiliensis: forty years of efforts in China

Good varieties are the basis for long-term high, stable and efficient production of rubber trees. Mini-seedling buddings have the characteristics of short nursery period, low labor intensity, large number of seedlings per unit area, easy transportation and planting, well-developed taproot and intact root system, high survival rate after planting, fast growth, strong tolerance to drought, wind and cold, and early tapping. The application of rubber mini-seedling buddings and its related research were summarized. Finally, the outlook for ongoing research on mini-seedling buddings was prospected.
