Abstract: RESTRIVERA ANGEL IZA, S., MORPHOLOGICAL CHARACTERIZATION OF COMMERCIALLY CULTIVATED Coffea spp. OF THE PHILIPPINES. Undergraduate Thesis. Bachelor of Science in Biology major in General Biology. Cavite State University Indang, Cavite. June 2019. Adviser Prof. Miriam Du Baltazar. Morphological characterization of commercially cultivated Coffea species of the Philippines across Cavite State University and Benguet State University Gene bank for the Cqffea arabica accessions was characterized using International Plant Genetic Resources Institute (IPGRI) and National Seed Industry Council (NSIC) descriptors for coffee on the basis of 21 morphological traits, four of which were qualitative and seventeen were quantitative traits. Most coffee samples had a roundish fruit shape, a marked but not prominent fruit disc shape. Entire leaf margin and per accessions are uniform in leaf architecture based on the qualitative traits. Regardless of collecting sites, generated dendograrn shows that the four Cqffea species are grouped separately. Based on the descriptive statistics, significant variation was observed in 17 quantitative traits among the 20 coffee accessions evaluated. Significant diversity (H'—>0.70) was also observed in all quantitative traits except for fruit disc shape having H'=0.48, Leaf margin (H'=0.62) and flower color (H"---0). For varietal improvement of coffee breeding programs, this level of diversity among coffee accessions shows that these accessions could be very useful in enriching the coffee germplasm.
