Pili (Canarium ovatum L.) is an endemic tree nut of the Philippines. It is among the plant species that have great potential to become major crop industry. While it is known for its delicious kernel which can be eaten raw, boiled or roasted. Its potential for industrial use remains largely unexplored. For this underutilized species to be effectively utilized, existing trees should be characterized and their production potential evaluated. A total of 135 accessions of pili maintained at the field genebank of the Institute of Plant Breeding were evaluated based on their morphological characteristics. Using the standardized Shannon-Weaver index (H') phenotypic diversity of the accessions based on 12 qualitative and 23 quantitative traits ranged from 0.35 to 0.86. The mean H' for qualitative traits (0.84) was higher than the quantitative traits (0.72). Four accessions were selected as promising accessions based on large kernel size and thin shell, and need further evaluation.
