Trial Planting of Fast-growing and High-yileding Rubber Clone Reken 523
After 10 years systematical observation on hevea clones of trials located in Hainan,Guangdong and Yunnan Province from 2000,it was found Reken 523 was a fast-growing and high-yielding clone.The annual stem increment reached 7.99 cm and could be cut one year earlier than normal clones.It had middle resistance to both powdery midew disease and rubber tree anthracnose.The resistance to wind injury was medium and TPD rate was lower than the control.At the same time,Reken 523 revealed high-yielding potential based on its latex physical diagnose.The main shortcoming was poor resistance to cold injury.But the cold injury was not remarkablly different from PR107 in 2008.This clone has great extention protential in Hainan and Yunnan where climatic type belongs to light wind and cold injury.
