Abstract
Conventional breeding methods have produced impressive results both for annual and perennial . crops. For example in maize carefully laid out breeding strategies resulted in a yield gain of almost 80 from 1930 to 1980 Duvick 1984. For the oil palm itself observation of fruit types their inheritance pattern and the subsequent exploitation of this knowledge in breeding practices resulted in a yield increase of up to 25 with the change over from the dura thick shelled to the tenera thin shelled planting material Hardon et aI. 1985. Although conventional breedin has produced impressive results it is not clear if historical rates of genetic gain can be sustained by using these methods alone. The oil palm one of the most important cultivated crops in Malaysia has shown signs of stagnation and in some cases a drop in oil extraction rates since 1986 Sharma et al. 1999. This reflects the urgency in producing new and improved varieties to ensure that productivity growth keeps pace with the rising demand. Molecular markers tagged to agriculturally important loci are ideal in assisting conventional breeding practices to achieve this aim. Furthermore since variety improvement through the use of markers does not involve transformation or integration of alien genes into the genome it is not complicated by the issues of biosafety and bioethics.
