xiv, 86 leaves : 29 cm. Morphological characterization and evaluation of the phenotypic diversity of 11 chili accessions were studied at the chili field genebank established at the Experimental Area of the Crop Research Laboratory at Mariano Marcos State University. The study aimed to (1) morphologically characterize chili germplasm collection using the International Plant Genetic Resources Institute (IPGRI) descriptors’ list for chili, and (2) evaluate the extent of phenotypic diversity among the collected germplasm for effective conservation and utilization. The experimental design that was used in the study was Descriptive Research Design. The study revealed variations in seedling characteristics such as hypocotyl pubescence, cotyledonous leaf color, and cotyledonous leaf shape. Hypocotyl pubescence varied from sparse to intermediate, while cotyledonous leaf color varied from light green to dark green. Stem color, stem pubescence, plant height, growth habit, canopy width, branching habit, leaf color, leaf shape, mature leaf length, and mature leaf width also varied. Inflorescence characteristics include the number of flowers per axil, flower position, and calyx margin. Fruit characteristics include fruit color at intermediate, set, mature, and fruit length, width, weight, pedicel length, and surface. Seed characteristics include seed surface and number of seeds per fruit, with variations in smooth to wrinkled surfaces and seed number. No variation in seed color was observed. The study highlights the importance of understanding and addressing these variations in seedlings for optimal growth and development. The study found variations in seedling, plant, inflorescence, fruit, and seed characteristics among eleven accessions, but similar phenotypic diversity in corolla shape, color, and fruit shape, indicating limited genetic variation, potentially impacting breeding programs.
