Abstract

The diversity in the morphological characters of 18 accessions of amaranth germplasm collection at National Plant Genetic Resources Laboratory (NPGRL) was investigated. This study will provide valuable information regarding the potential of the germplasm collections as well as identify gaps for future collecting missions. These germplasm materials have been collected from 10 different provinces in the Philippines. Morphological characterization was conducted using standard descriptors published by International Board for Plant Genetic Resources (1981). A total of 34 characters comprising 22 qualitative and 12 quantitative data were observed. Based on Shannon-Weaver Diversity Index, 17 characters (50%) were found to have high diversity (>0.67) while two characters were invariant. Using Gower’s coefficient at 0.7 r2, five clusters were generated from all the morphological characters. Following the taxonomic key, 4 species A. spinosus, A. gracilis, A. hybridus, and A. tricolor were identified in the 18 accessions used in the study. The results of the taxonomic identification and cluster analysis agree with each other.
