Broadening the genetic base of oil palm was as a key action for the improvement of the crop. In this study, fourteen tenera progenies from MPOB-CMR x MPOB-CMR and MPOB-CMR x MPOB-ZRE (T x T), crossed according to bi-parental mating design (BIP) were assessed in their fresh fruit bunch (FFB), bunch number (BNO) and average bunch weight (ABWT). The progenies were planted following a randomized complete block design (RCBD) in two replicates. Analysis of variance (ANOVA) revealed that the variability among progenies, for FFB, BNO and ABWT, were highly significant. The contribution of the environmental effects is relatively high for BNO, and this is shown by the low heritability estimated on this character. On the other hand, ABW character showed a high heritability (h 2 B > 50%) at 67.31%. Progenies deriving from MPOB-CMR x MPOB-ZRE crosses have shown a significantly higher performance compared to those from MPOB-CMR x MPOB-CMR x MPOB-CMR for FFB. Progeny PK1943 (MPOB-CMR x MPOB-ZRE) is the best performer with an average bunch yield of 175.29 kg palm −1 yr −1 .
