ROSERO ERAZO, Jhon Alexander et al. Combinatory ability of yield in Golden berry (Physalis peruviana L.) inbred lines. Acta Agron. [online]. 2021, vol.70, n.4, pp.345-352.  Epub 29-Mar-2023. ISSN 0120-2812.  https://doi.org/10.15446/acag.v70n4.79049.

The golden berry Physalis peruviana native to the inter-Andean valleys of South America, is currently one of the most relevant exotic fruits for Colombia, its demand for export seeks to possess ideal traits of yield and fruit quality. The objective is to determine the genetic parameters of Combinatory Aptitude of nine inbred lines of Uchuva under conditions of the Andean natural region of the department of Nariño. 36 hybrids of cape gooseberry obtained from nine inbred lines 12U347, 12U350, 12U352, 12U357, 12U360, 12U368, 12U374, 12U377, and 12U39, in four localities of the department of Nariño: Gualmatán, Puerres, Pasto, and Ipiales, in order to determine the effects of general (GCA) and specific (SCA) combining ability on performance. The commercial yield (CY) and the agronomic yield (AY) are evaluated in a dialellic under method IV of Griffing (1956). The combined analysis of variation indicates significant differences in the genotype-environment interaction for CY and AY across all localities. The Combinatorial Aptitude analysis reported that additive and non-additive effects are important in AY and CY. The best hybrids in Gualmatán were 7x8, 3x5 and 3x7, in Ipiales 2x9, 1x3 and 4x8, in Pasto 1x7, 1x3 and 7x8, and in Puerres 2x5, 2x8 and 2x3, which can be taken into account to be used as commercial hybrids high yield.
