Abstract
The oil palm Elaels guineensis acq. has two fruit colour forms: nigrescens Nig unripe fruits deep violet ripening to reddish orange and virescens Vir immature fruits green ripening to bright orange. Vir is monofactorially dominant over Nig. Fruit colour change during ripening is more obvious in Vir and could be exploited as a harvesting criteria as the present practice of waiting for abscinding fruits requires considerable labour to collect the fruits. Molecular markers would be very useful in Vir breeding as oil palms take about three years to bear fruits. A preliminary screening of 64 commercial AFLP primers showed 10 to be informative for the two populations studied a CBP and a NPC cross from a Pamol Plantations virescens breeding programme. Three fragments were found to closely tag the trait in a BSA sample of 10 individuals for each colour type from each population. When tested on the full populations two E-ACT/M-CAT fragments 142.13 bp and 355.76 bp long respectively distinguished Vir with 83 accuracy in CBP and NPC while a 253.79bp fragment from E-ACT/M-CTA distinguished Nig with 77 accuracy in both populations.
