Yield potential of various sources of planting materials in Malaysia : second round evalution
A total of 100 dura x pisifera (DxP) progenies from seven seed producers (agencies) in Malaysia were evaluated in a comparative trial in Lahad Datu, Sabah, Malaysia. The trial mean for fresh fruit bunch (FFB) was 168.18 kg palm-1 yr-1 and the oil to bunch (O/B) was 22.73%. High FFB yield was largely attributed to the high bunch number (BNO), while reduced O/B was probably due to low fruit to bunch (57.26%) and oil to dry mesocarp (75.31%). Agency 6 was outstanding for bunch yield, oil per palm per year, kernel per palm per year and hence, total economic product. Agency 5 was exceptional for bunch and fruit qualities. Statistical analyses suggested that performance of the planting materials from the various agencies differed significantly for bunch yield and bunch quality components. Differences in performance among the agencies (populations) were largely due to the genetic background of the materials.
