description The species of the genus Portulaca are widely used in gardening for potted plants and for outdoor decoration. They are easy to plant, have minimal requirements, add beauty to a particular environment and are a valued resource for landscaping. The ornamental plant market is very dynamic and is eager to frequently incorporate new varieties and hybrids. For these reasons, the objective of this research is: to create new hybrids of Portulaca umbraticola through intraspecific crosses. Crossings were made between four cultivars of P. umbraticola with flowers of different colors (white, red, red-fusia and bicolor yellow-fusia) under a partial diallel design without incorporating self-pollinations. After the pollinations were carried out, the percentage of fruit set, the number of seeds and the percentage of germination were measured in each cross. An average of fruit formation percentage of 42.5%, 13.5 seeds per fruit and a germination percentage of 22.5% were obtained. As a result, hybrids with similar morphological characteristics were obtained in each cross, however, they presented different interesting coloring patterns in the flower and foliage. All hybrids, except those of the fourth cross, showed novelty phenotypic changes. Possible inheritance patterns for flower color are also analyzed. By presenting these new phenotypes, they can be considered as material to develop new cultivars with ornamental and landscape interest. The intraspecific hybridization of P. umbraticola is an effective technique for the genetic improvement of the specie and obtaining new cultivars.

Las especies del género Portulaca son muy utilizadas en jardinería para planta en maceta y para decoración de exteriores. Son fáciles de cultivar, poseen requerimientos mínimos, aportan belleza a un ambiente particular y constituyen un valorado recurso para el paisajismo. El mercado de plantas ornamentales es muy dinámico y se muestra ávido de incorporar frecuentemente nuevas variedades e híbridos. Por tales razones, el objetivo de la presente investigación es: crear nuevos híbridos de P. umbraticola a través de cruzamientos intraespecíficos. Se realizaron cruzamientos entre cuatro cultivares de P. umbraticola con flores de diferentes colores (blanca, roja, roja-fusia y bicolor amarillo-fusia) bajo un diseño de dialelo parcial sin incorporar autopolinizaciones. Después de realizadas las polinizaciones, se midió el porcentaje de formación de frutos, cantidad de semillas y porcentaje de germinación en cada cruzamiento. Se obtuvo en promedio un % de formación de frutos de 42,5%, 13,5 semillas por fruto y un % de germinación de 22,5%. Se obtuvieron híbridos con características morfológicas similares en cada cruzamiento, sin embargo, presentaron diferentes patrones de coloración interesantes en la flor y follaje. Todos los híbridos, excepto los del cuarto cruzamiento, mostraron cambios fenotípicos novedosos. También se analiza los posibles patrones de herencia para el color de fl or. Al presentarse estos nuevos fenotipos pueden considerarse como material para desarrollar nuevos cultivares con interés ornamental y paisajístico. La hibridación intraespecífi ca de P. umbraticola es una técnica efectiva para el mejoramiento genético de la especie y la obtención de nuevos cultivares.
