General and specific combining abilities in a lulo diallel cross (Solanum quitoense Lam.)
Lulo (Solanum quitoense) is a promising agro-industry fruit tree, not only because of its nutritional value, taste, and appearance but also because it provides an alternative production system in mild and moderately cold climate zones.

| description | Lulo (Solanum quitoense) is a promising agro-industry fruit tree, not only because of its nutritional value, taste, and appearance but also because it provides an alternative production system in mild and moderately cold climate zones. Lulo crop yield and production in the Department of Nariño (Colombia) has decreased in recent years when compared to other producing regions in Colombia. Therefore, the objective of this study was to estimate the effects of the general combining ability (GCA) and the specific combining ability (SCA) in a diallel cross of 10 promising parents in four growing regions of the Department of Nariño for use in breeding programs. A total of 45 hybrid combinations were obtained and assessed with Griffing method 4. The following variables were assessed: days to flowering onset (DFO), number of clusters per branch (NCB), fruit weight (FW), polar axis (PA) of the fruit, and yield (Y). The analysis of variance showed statistical differences for most variables in response to single-cross hybrid effects and locations, except for NCB and Y. Moreover, significant differences were found for the interactions between the GCA and SCA and the hybrids and locations, respectively, meaning that environment must be considered when selecting parents with specific adaptability. The effects of the GCA and SCA promoted higher positive values for the FW and Y in parents 4, 6, and 8 and their combinations. Therefore, these parental genotypes are promising for lulo genetic improvement programs since their additive effects and genetic dominance favor fruit weight and yield. |

El lulo (Solanum quitoense) es un árbol frutal prometedor para la agroindustria, no sólo por su valor nutritivo, su sabor y su aspecto, sino también porque constituye un sistema de producción alternativo en zonas de clima templado y moderadamente frío. El rendimiento de los cultivos y la producción de lulo en el Departamento de Nariño (Colombia) han disminuido en los últimos años en comparación con otras regiones productoras del país. Por lo tanto, el objetivo de este estudio fue estimar los efectos de la habilidad combinatoria general (HCG) y la habilidad combinatoria especifica (HCE) en un cruzamiento dialelico de 10 progenitores promisorios en cuatro regiones del Departamento de Nariño, que pueden considerarse en los programas de mejoramiento. Se obtuvieron un total de 45 combinaciones híbridas obtenidas con el método 4 de Griffing. Se evaluaron las siguientes variables: días para el inicio de la floración (DIF), número de racimos por rama (NRR), peso del fruto (PF), eje polar (EP) del fruto y rendimiento (RTO). El análisis de la varianza mostró diferencias estadísticas para la mayoría de las variables en respuesta a los efectos de los híbridos y a las localidades, excepto para NRR y RTO. Además, se encontraron diferencias significativas para las interacciones del HCG y HCE con los híbridos y las localidades, respectivamente, demostrando que debe considerarse el medio ambiente para seleccionar los progenitores con una adaptabilidad específica. Los efectos del HCG y HCE presentan valores positivos altos para PF y RTO en los parentales 4, 6 y 8 y en sus combinaciones. Por lo tanto, estos parentales son promisorios para los programas de mejoramiento genético del lulo, ya que sus efectos aditivos y de dominancia favorecen el peso y el rendimiento del fruto.
