| description | Classic plant breeding, based on the selection of superior individuals and directed crosses, led to the need-to-know aspects of the floral biology of cowpea beans. The research was carried out at the Universidad de Córdoba, Colombia, through two experiments: in the first, stigmatic receptivity was evaluated as response time to hydrogen peroxide, under a randomized complete block design, with a 3×4 factorial arrangement (three genotypes: Caupicor 50, Missouri and BRS Milenium, and at four hours of the day: 7:00 and 9:00 AM; 3:00 and 5:00 PM) and three replications. In the second, the percentage of viable crosses was evaluated, under a randomized complete block design, with a 2×2 factorial arrangement (two crosses: Missouri × IT86 and Missouri × BRS Milenium, and two methods: 1 (morning) and 2 (afternoon), and four replications. The greatest stigmatic receptivity was recorded in the BRS Milenium and Missouri genotypes with a time of 3.28±0.07 and 2.01±0.12 min at 7:00 and 9:00 AM, while Caupicor 50, time of 1.80±0.09 min at 3:00 PM. The artificial hybridizations carried out in the morning (method 1) registered the highest viable crosses, 78.6% in Missouri × BRS Milenium and 57.1% in Missouri × IT86. Therefore, artificial hybridizations should be done in the morning due to a more favorable environment for pollen grain germination, given the greater stigmatic receptivity. |

El mejoramiento genético clásico, basado en la selección de individuos superiores y cruzamientos dirigidos, demanda conocer aspectos de la biología floral y reproductiva del fríjol caupí. La investigación se llevó a cabo en la Universidad de Córdoba, mediante dos experimentos: en el primero, se evaluó la receptividad estigmática como tiempo de respuesta al peróxido de hidrógeno, bajo el diseño bloques completos aleatorizados con arreglo factorial 3×4 (tres genotipos: Caupicor 50, Missouri y BRS Milenium, y cuatro horas del día: 7:00 y 9:00 AM, 3:00 y 5:00 PM) y tres repeticiones; en el segundo, se evaluó el porcentaje de cruzamientos viables, bajo un diseño Bloques Completos al azar con arreglo factorial 2×2 (dos cruzamientos: Missouri × IT86 y Missouri × BRS Milenium, dos métodos: 1 (mañana) y 2 (tarde), y cuatro repeticiones. La mayor receptividad estigmática se registró en los genotipos BRS Milenium y Missouri, con tiempo de 3,28±0,07 y 2,01±0,12 min a las 7:00 y 9:00 AM, mientras que Caupicor 50, tiempo de 1,80±0,09 min a las 3:00 AM. Las hibridaciones artificiales realizadas por la mañana registraron los mayores cruzamientos viables, 78,6% en Missouri × BRS Milenium y 57,1% en Missouri × IT86. Por tanto, las hibridaciones artificiales deben hacerse en horas de la mañana debido a un ambiente más propicio para la germinación del grano de polen, dada la mayor receptividad estigmática.
