【 摘 要 】

The clonal and inter-clonal combining ability of fruit set in a Hevea brasiliensis four-parent diallel mating was evaluated using a randomized complete block experimental design with three replicates. Twelve main and reciprocal crosses were hand pollinated and percentage fruit set was recorded. The raw data were subjected to an arc-sine transformation for analysis of variance, and general and specific combining ability. There was significant variation of each of fruit set for the various crosses, general combining ability and reciprocal effect. The breeding implications of these results are also discussed.
