The objective of this study was to evaluate the pollen viability, stigmatic receptivity and agronomic behavior of three hybrids of Portulaca umbraticola obtained in 2021, Tekila Sunset, Coral Lipstick and Star Blush in comparison to commercial cultivars pink, yellow and orange from Vigrow Seeds®. Measurements were taken in five quantitative and five qualitative variables for the agronomic evaluation. Pollen viability and stigmatic receptivity were evaluated using 1% acetic carmine staining and with hydrogen peroxide, respectively. Significant differences were obtained in the quantitative variables (p≤0,05), with the commercial cultivars being the largest. In terms of pollen viability, the cultivars with the lowest and highest amount of viable pollen were Coral Lipstick and Tekila Sunset with 17,4% and 91.6%, respectively. There were significant differences (p≤0,05) in terms of cultivars, timing and cultivar × timing interaction for stigmatic receptivity, which was greater in the range of 11:00-3:00 p. m. for most cultivars. Agronomically adapted hybrids with novel coloring patterns were obtained for the ornamental market. In future breeding programs, it is recommended to take as male parents those with the highest pollen viability and carry out pollinations in the time range where the stigma is most receptive. Portulaca umbraticola es una planta ornamental de la familia Portulacaceae muy utilizada en jardinería. El objetivo de este estudio fue evaluar la viabilidad polínica, receptividad estigmática y comportamiento agronómico de tres híbridos de Portulaca umbraticola obtenidos en el 2021, Tekila Sunset, Coral Lipstick y Star Blush, en comparación a cultivares comerciales de color rosa, amarillo y naranja de Vigrow Seeds®. Se tomaron mediciones en cinco variables cuantitativas y cinco cualitativas para la evaluación agronómica. La viabilidad polínica y receptividad estigmática se evaluaron mediante la tinción con carmín acético al 1% y peróxido de hidrógeno respectivamente. Se obtuvieron diferencias significativas en las variables cuantitativas (p≤0,05), siendo los cultivares comerciales los de mayor magnitud. Los cultivares de menor y mayor cantidad de polen viable fueron Coral Lipstick y Tekila Sunset con 17,4% y 91,6%, respectivamente. Hubo diferencias significativas (p≤0,05) en cuanto a cultivares, horarios e interacción cultivar × horarios para la receptividad estigmática, la cual fue mayor en el rango de 11:00-3:00 p. m. para la mayoría de los cultivares. Se obtuvieron híbridos agronómicamente adaptados con patrones de coloración novedosos para el mercado ornamental. En futuros programas de mejoramiento se recomienda tomar como parentales masculinos los de mayor viabilidad polínica y realizar las polinizaciones en el rango horario donde el estigma se encuentra más receptivo.
