Genetic variability of oil palm (Elaeis guineensis Jacq.) deli dura inter-crosses population in the MPOB research station Hulu Paka, Terengganu, Malaysia

The oil palm Deli dura breeding population is the most widely used dura for breeding and seed production. Due to its narrow genetic base, with current material originating from the four initial dura palms of Bogor, the Deli dura is presumed to have low genetic diversity. A total of 35 MPOB Deli dura...
