Genetic diversity and selection criteria of MPOB-Senegal oil palm (Elaeis guineensis Jacq.) germplasm by quantitative traits

Understanding genetic structure of different vegetative, yield and yield component traits play a major role in oil palm breeding program. Based on this background, this study was carried out to evaluate the genetic diversity and heritability among 26 families of MPOB-Senegal oil palm germplasm using...

Based on this background, this study was carried out to evaluate the genetic diversity and heritability among 26 families of MPOB-Senegal oil palm germplasm using multivariate analysis to identify superior palms for future oil palm breeding program. To achieve this objective, data on yield components, bunch quality and vegetative traits were collected for eight consecutive years.
