橡胶树矮生高产材料热研87-4-26选育初报

Primary Report for Selection and Breeding of Dwarfing and High-yield Clone,SCATC87-4-26

热研87－4－26为热研88－13×热研217杂交后代第3、4割年平均株次干胶为111.89g，干胶产量是对照的225.1％。生长比对照RRIM600慢，11年生时全树高13.7m，比对照矮15%，是一个早熟、高产、稳产的矮生材料。

：It was showed that SCATC87-4-26 is an early-maturing, stable high-yield and dwarfing rubber material in the primary test trial for four tapping years. The mean yield of dry rubber of the third and fourth tapping years was 11l.8g/t/t. with 125.5% higher than the control clone RRIM600.The girth was slower than that of the control. and the height of tree is 13.7 meters at eleven years, about 85% height against the control.
