“…Conventionally, morphological traits had been used to differentiate plant germplasm/ species and to elucidate their genetic relationship (Sibut et al, 2023). As in this study, high values were observed in the coefficients of variation in the characteristics associated with the cladode and the sprouts, in the evaluated locations.…”

“…A previous study showed that morphoagronomic characterizations could be used to determine the variation in natural pitahaya populations (Abirami et al, 2021). Sibut et al (2023) evaluated yield capacity of six superior pitaya genotypes under edaphoclimatic conditions of the Federal district in Brazil, found genotypes with good physical characteristics, performance and adapted to local conditions.…”

Selenicereus megalanthus Haw. It is an exotic fruit tree, with productive and nutritional potential. In Colombia, there is a great phenotypic and genotypic diversity, but its genetic studies are scarce. The objective was to characterize morphologically 15 selected yellow pitahaya genotypes, under two productive systems in the open field and under cover, in the municipalities of Miraflores and Zetaquira, in Boyacá, Colombia. Quantitative characters were evaluated: plant height (PH), number of vegetative sprouts (NVS), sub-sprouts (SS), longest sprouts length (LSL), distance between areoles (DBA), width of the ribs in the apical region (WRA), width of the ribs in the middle region (WRM), width of the ribs in the basal region (WRB), height of undulations between successive areoles in a rib (HUA), number of spines per areole (NSA) and longest spine length (LSP). The results showed under the two productive systems and the evaluated localities that the variables with the highest coefficient of variation (greater than 90%) were the number of sub-sprouts, height of the undulations between successive areoles (HUA) and the longest spine length (LSP). High positive correlations were obtained between the distances areoles, the width of the ribs and the length of the spines (r>0.7). The conglomerate showed that the characteristics that define the groupings are height of the plant, the texture of the cladodes, the width of the ribs and the height of the undulations. Characters associated with the shoots and cladodes were identified, which directly influence the vegetative propagation and therefore the yield of the yellow pitahaya.
