MORILLO-CORONADO, ANA CRUZ; GONZALEZ-CASTILLO, JOSE ALEJANDRO  and  MORILLO-CORONADO, YACENIA. CHARACTERIZATION OF GENETIC DIVERSITY UCHUVA (Physalis peruviana L.) IN BOYACÁ. Rev.Bio.Agro [online]. 2018, vol.16, n.1, pp.26-33. ISSN 1692-3561.  https://doi.org/10.18684/bsaa.v16n1.631.

Cape gooseberry, Physalis peruviana L. is a tropical fruit tree native to the Andean region, presenting primary and secondary metabolites that confer antioxidant, anti-inflammatory and anticancer properties. It is currently the second export fruit in Colombia, with Boyacá being one of the departments that contributes most to national production. Therefore, the objective of this research was to characterize the genetic diversity of Cape gooseberry in the Department of Boyacá. A collection of 15 wild materials from P. Peruviana was carried out in the municipalities of Paipa, Combita, Tuta, Sotaquirá, Santa Rosa de Viterbo and Tunja and were characterized with seven RAMs microsatellite markers. The analysis by the Nei-Li coefficient at a similarity level of 0,65 differentiated the population in three groups according to the site of origin of the materials. The average Heterocigosidad value was 0,27, which is considered low compared to other genetic diversity studies. The analysis of Molecular variance (AMOVA) and the Fst show the existence of genetic variability at the intraspecific level which should be retained and used in the genetic improvement that allows the obtaining of adapted materials, with characteristics agronomic, nutritional and medicinal of high quality.
