    Abstract

    Rambutan (Nephelium lappaceum) breeding research was started in 1981 in Malaysian Agricultural Research and Development Institute (MARDI). Ten thousand open-pollinated seeds from two maternal parents (R99 and R134) and 14 paternal parents (R3, R4, R7, R9, R137, R139, R153, R156, R157, R160, R161, R162, R168 and R170) were collected to generate F1 progeny. Four stages of step-wise culling were applied during selection and resulted in 40 promising progeny. These plants were investigated to determine whether any are the products of selfing. Reproductive studies on these progenies were carried out: results on the pollen viability, compatibility and percentage of male flowers in a panicle were obtained. The percentage of male flowers produced ranged from 2.3% (IJ-06) to 19.8% (AD- 47). In comparison, the maternal parents produced 5.7% (R99) and 7.0% (R134) male flowers. The highest pollen viability was recorded in progeny AD-47 (94%) and the lowest in progeny IJ-06 (60%) whereas R99 and R134 have 76% and 88% pollen viability respectively. The results from bagging studies showed fruit set ranged from 0% (AD-47) to 0.70% (IF-20) in comparison to maternal parents R99 (0.23%) and R134 (0.35%). The study showed that rambutan produces male flowers and fertile pollen but the occurrence of self-pollination is low. The status of these F1 progenies can be confirmed by the use of molecular techniques.
