| description | The creole melon cantaloupe is a horticultural species, whose fruits are used for human nutrition. However, no research has been reported on their genetic variability for starting breeding processes. The objective of this study was to take advantage of the variability of creole melons for genetic improvement. 20 creole melon half-sib families were selected and evaluated for production characteristics and fruit quality in order to obtain improved populations. The study was carried out in Palenque canton, Ecuador. Seeds from 20 half-sib families were used, arranged in a randomized complete block design with three replications. The differences between the families were significant for all the studied characteristics. Family 93 presented higher averages for fruit weight, fruit diameter and production (per hectare), and family 196 did so for soluble solids. The phenotypic correlations were positive and significant between the fruit weight and fruit diameter, fruit length, pulp thickness, fruit cavity, soluble solids and production. The coefficients of genetic variation, in general, were lower than the coefficients of environmental variation. The estimates of heritability broadly had a moderate magnitude (30-60%) for the 10 evaluated characteristics, and the magnitude of the expected genetic progress was low (<10%) for the fruit weight, production, and soluble solids, so the selection for high production should focus on fruit weight and soluble solids. |

El melón criollo de tajada cantalupo es una especie hortícola, cuyos frutos son utilizados en la alimentación humana. Sin embargo, no se han reportado investigaciones de su variabilidad genética para iniciar procesos de mejoramiento. El objetivo de esta investigación fue aprovechar la variabilidad de los melones criollos para mejorarlos genéticamente, mediante selección. Se seleccionaron y evaluaron 20 familias de medios hermanos de melón criollo de tajada por características de producción y calidad del fruto, con el fin de obtener poblaciones mejoradas. El estudio se realizó en el cantón Palenque, Ecuador. Se utilizó semilla de 20 familias de medios hermanos, dispuestas en un diseño de bloques completos al azar con tres repeticiones. Las diferencias entre familias fueron significativas para todos los caracteres estudiados. La familia 93 presentó mayores promedios para peso de fruto, diámetro de fruto y producción (por hectárea) y la familia 196 para sólidos solubles. Las correlaciones fenotípicas fueron positivas y significativas entre el peso de fruto y el diámetro de fruto, longitud del fruto, espesor de la pulpa, cavidad del fruto, sólidos solubles y producción. Los coeficientes de variación genética, en general, fueron menores que los coeficientes de variación ambiental. Las estimaciones de heredabilidad en sentido amplio fueron de magnitud moderada (30-60%) para los 10 caracteres evaluados y la magnitud del progreso genético esperado fue baja (<10%) para peso de fruto, producción, y sólidos solubles, por lo que se considera que la selección para melones de alta producción debe enfocarse en peso del fruto y sólidos solubles.
