The utilization of the 1981 IRRDB Hevea germplasm is very slow in China. For further characterization and evaluation of the germplasm, an analysis was made to evaluate the characteristics of latex regeneration and latex flow of the new Amazon Hevea germplasm by the method of latex diagnosis. Nine accessions of the germplasm were determined in terms of physiological parameters such as yield, initial flow rate, plug index, sucrose, thiols, phosphorus, magnesium, etc, with RRIM600 as the control.
