| description | Cowpea beans are the most important legume in the Caribbean region of Colombia. This grain is produced mainly by small farmers in rural agriculture but is becoming more important every year for commercial agriculture. The objective of this study was to estimate heritability, genetic gain and correlations between agronomic characteristics and the nutritional content of 30 cowpea bean cultivars. The number of days to flowering (NDF), number of pods per plant (NPP), number of pods per peduncle (NPPE), peduncle length (PEL), number of nodes on main stem (NNMS), grain length (GL), grain width (GW), weight of 100 seeds (W100S), iron content (FeC), zinc content (ZnC), protein content in percentage (PROT) and YIELD were evaluated. Likewise, the genetic parameters: phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV), variability index (b), heritability [(h2 (%)], genetic gain (GG) and genetic progress (%), together with phenotypic correlations and genetic correlations, were determined. Genetic variability was evidenced in the population (P<0.05), except for PEL. The highest heritability was in W100S, ZnC and FeC (h2A> 96%). The greatest advance was achieved in ZnC, FeC, W100S and YIELD, with values higher than 30%, indicating the potential use of the evaluated genotypes for improving this species and positive and significant phenotypic and genotypic correlations between YIELD and PROT. Therefore, cultivars with higher yields and protein contents can be obtained. |

El fríjol caupí es la leguminosa más importante de la región Caribe de Colombia, cuyo grano es producido principalmente por pequeños productores en la agricultura campesina, pero que cada año cobra más importancia en la agricultura empresarial. El objetivo del estudio fue estimar heredabilidad, avance genético y correlaciones entre características agronómicas y contenido nutricional de 30 cultivares de fríjol caupí. Fueron evaluados los caracteres número de días a floración (NDF), número de vainas por planta (NVP), número de vainas por pedúnculo (NVPE), longitud del pedúnculo (LPE), número de nudos del tallo principal (NNTP), longitud del grano (LG), ancho del grano (AG), peso de 100 semillas (P100S), contenido de hierro (CFe), contenido de zinc (CZn), contenido de proteína en porcentaje (PROT) (%P) y rendimiento (REND). Así mismo, los parámetros genéticos: coeficiente de variación fenotípico (CVF), coeficiente de variación genotípico (CVG), índice de variabilidad (b), heredabilidad [(h2 (%)], ganancia genética, progreso genético genética en la población (P<0,05), excepto para LPE. La heredabilidad más alta, en sentido amplio se presentó en P100S, CZn y CFe (h2A>96%). El mayor avance se logró en CZn, CFe, P100S y REND, con valores superiores al 30%, lo que denota la posibilidad de hacer uso de los genotipos evaluados para mejorar la especie. Así mismo, correlaciones fenotípicas y genotípicas positivas y significativas entre REND y PROT, lo que posibilita la obtención de cultivares de mayor rendimiento y contenido de proteína.
