Abstract The validity of two forgotten names, EryphusKlug, 1829 and E. rubricollisKlug, 1829, is discussed. The former is considered a nomen oblitum and synonymized with EriphusAudinet-Serville, 1834, a nomen protectum; the latter is revalidated and Eriphus purpuratus Chevrolat, 1862 is considered a junior synonym of Eriphus rubricollis (Klug, 1829).

Estimates of genetic parameters allow to determine the genetic variability present in a population, constituting one of the initial steps in a breeding program. The objectives of this study were to estimate genetic parameters and identify agronomic traits directly and indirectly correlated with grain yield (GY), as well as to estimate their direct and indirect effects on the yield of special-grain common bean genotypes. The experiment was carried out in the 2016/2017 season, in a complete blocks design, with three repetitions. The evaluated traits were days to flowering, days to maturity, first pod height, plant height, number of pods per plant, number of grains per pod, mass of hundred grains, and grain yield. Data were subjected to analysis of variance, and genetic parameters were estimated followed by phenotypic and genotypic correlations. Phenotypic and genotypic correlations were split into direct and indirect effects by path analysis. The studied population seemed promising for breeding purposes considering most traits. Correlation and path analyses indicated that there was a positive direct effect of days to maturity on grain yield. The traits days to maturity and mass of hundred grains can be used in indirect selection aiming at higher grain yield. Path analysis also revealed that the indirect effects of number of pods per plant and number of grains per pod should be taken into consideration in the genetic breeding of the common bean for the increased grain yield.

Las estimaciones de los parámetros genéticos permiten determinar la variabilidad genética presente en una población y constituyen uno de los pasos iniciales de un programa de mejoramiento genético. El objetivo de este trabajo fue estimar los parámetros genéticos, identificar los caracteres agronómicos que se correlacionan directa e indirectamente con la productividad del grano, así como estimar sus efectos directos e indirectos sobre la productividad de diez genotipos de frijol común de grano especial. El experimento se realizó en la campaña agrícola 2016/2017 en diseño de bloques aleatorios, con tres repeticiones. Los caracteres evaluados fueron: días hasta la floración, días hasta la maduración, altura de inserción de la primera vaina, altura de la planta, número de vainas por planta, número de granos por vaina, masa de cien granos y rendimiento de granos. Los datos obtenidos se sometieron al análisis de varianza y se estimaron los parámetros genéticos seguidos de correlaciones fenotípicas y genotípicas. La población estudiada ha demostrado ser prometedora para la mejora de la mayoría de los caracteres evaluados. Hubo un efecto directo positivo de los días hasta la maduración en el rendimiento de granos. Los caracteres días hasta la maduración y masa de cien granos pueden ser utilizados en la selección indirecta con el fin de obtener un mayor rendimiento de granos.
