The present study was carried out with the objectives of morphologically characterizing and molecularly characterizing different genotypes of Coffea canephora and evaluating the behavior of their progeny located in the Germplasm Bank and Nursery of the IRD “Fundo Génova” in Chanchamayo during the 2018-2019 campaign. For the morphological characterization, 26 quantitative variables and 17 qualitative variables were evaluated that were taken from minimum descriptors established for Coffea canephora, of which the mean, standard deviation, minimum, maximum and coefficient of variability were evaluated, among the most important results were noted the null presence of coffee rust in the different genotypes, as well as marked differences in some productive variables. In the molecular characterization, the DNA was extracted and 4 ISSR-type primers out of a total of 10 were effectively used to differentiate the genetic variability of the different genotypes of Coffea canephora, the results of the dendrogram show that there is a notorious genetic variability between individuals belonging to the same accession. Finally, for the analysis of the behavior in the nursery of the progeny of the mother genotypes, the germination percentage of 1100 seeds distributed at random was evaluated, of which 150 seedlings were picked in polyethylene bags, where the number of leaves was evaluated, plant height and stem diameter per plant. Subsequently, 93 seedlings were extracted for the measurement of fresh weight and dry weight. The average results suggest a germination percentage of 78.64%, a number of leaves of 7.48, a height of 9.31 cm, a stem diameter of 0.25 cm, a fresh weight of 2.54 gr and a dry weight per plant of 1.25 gr.
