To further exploit the yield increasing potential of Hevea brasiliensis clone RRIM600, correlation, path coefficient and stepwise regression analyses were conducted to analyze the constitutions including the number of tappable trees, dry rubber yield per tree per tap and the number of tapping etc. of RRIM600 which is a season–long crop under tapping ages of 9, 15, 17, 18, 19, 20, 21, 23, 29 and 33 years. The result indicated that there was big difference in dry rubber yield of RRIM600 among the ten ages of tapping, among which the highest yield was in tapping age of 17 years (1 273.94 kg/hm2), while the lowest yield was in tapping age of 18 years (471.06 kg/hm2). Among the 5 yield traits，the number of tappable trees per hectare showed the biggest contribution to yield, followed by mean dry rubber yield gram per tree per tapping, survival rate of trees, the number of tapping per year, and tapping tree percentage; Increasing the number of tappable trees per hectare is the most effective way to increase the yield of RRIM600, followed by increasing the mean dry rubber yield gram per tree per tapping and the number of tapping per year. The variation coefficient of the number of tappable trees per hectare during different tapping ages was the highest (25.71%), followed by mean dry rubber yield gram per tree per tapping (23.45%); the number of tapping per year showed the lowest (9.67%) variation coefficient. In conclusion, to achieve the maximum yield and benefit, the breakthrough should be increasing the number of tappable trees per hectare and mean dry rubber yield gram per tree per tapping based on the optimum number of tapping per year, and fully coordinating the relationship among the three indexes.
