Description: The usefulness of collecting latex as yield in test-tapping of Hevea seedlings for juvenile selection was assessed. Latex volume was recorded as yield instead of dry rubber. Data were recorded from each tapping for each of the test-tapped seedlings using graduated microcentrifuge/centrifuge tubes. Dry rubber content (DRC) of top selections was determined for calculation of rubber yield. Mean range in latex yields among the tapped seedlings was 0.07 mL t1 t1 to 16.46 mL t1 t1 (mL per tree per tapping). Mean rubber yields in the top 20% selections from 10 tappings varied from 4.25 g t1 10t1 to 41.37 g t1 10t1 (grams per tree per 10 tappings). DRC among the top 20% selections varied from 14.3% to 38%. It was concluded that in juvenile selection of Hevea seedlings, yields determined as latex volume could result in more accurate yield recordings. Furthermore, the latex could be used to determine rubber content for eliminating the very low DRC seedlings. Information on biochemical and physiological determinants of yield could also be extracted in an effort to enhance probability of potential selections.
