AbstractThe yellow pitahaya, Selenicereus megalanthus (K. Schum. ex Vaupel) Moran, is considered an exotic fruit and is an essential product for the horticulture sector with significant demand mainly due to its flavor, appearance, quality, and nutrapharmaceutical properties. In addition, it has mark...

description AbstractThe yellow pitahaya, Selenicereus megalanthus (K. Schum. ex Vaupel) Moran, is considered an exotic fruit and is an essential product for the horticulture sector with significant demand mainly due to its flavor, appearance, quality, and nutrapharmaceutical properties. In addition, it has marketing potential, both domestically and internationally. Boyacá has pioneered the domestic production of pitahaya, which is why the present study aimed to identify the genetic variability that exists in the municipalities that produce it in the province of Lengupá with a morphological characterization of 25 materials using 27 descriptors, of which 18 were quantitative and 9 were qualitative, for the phylloclades and fruits. A principal components analysis was used to determine the principal morphological characteristics that allowed for differentiation of the materials: rib width (RW),  height of the undulations between successive areolas in a rib (UH), fruit length (FL), fruit width (FWI), length of the longest apex bract (LAB), equatorial bract length (LEB), fruit weight (FW), peel weight (PW), pulp/peel ratio (PPR), soluble solids (SS), fruit shape (FS). The heirarchical cluster analysis resulted in four groups that corresponded to where the materials were collected. The genetic diversity of these materials was higher than that reported in other studies of the yellow pitahaya in this country, but it is necessay to create alternatives for increasing this diversity and effeciaently using it in conservation and breeding programs.  ResumenLa pitahaya amarilla, Selenicereus megalanthus (K.
