The size and color of its flowers make it very attractive for ornamental cultivation. The development of domestication and breeding protocols are essential to propose it as a new crop, considering that the global floricultural industry requires novelties. As a starting point, compatibility and reproductive efficiency studies were carried out through controlled crosses considering phenotypes of flowers of different color. Both self-pollination and cross-pollination produced fruits, so a mixed reproductive system was verifi ed in R. bifida. Reproductive efficiency was significantly higher in cross-pollination than in self-pollination, being 49.6 and 19 respectively, for red flowers, the most representative genotype of the population. No fruiting was observed in emasculated flowers without pollination, so autonomous apomixis was ruled out. The crossings among phenotypes produced fruits except for the case of crossings between pink by fuchsias flowered phenotypes. Rhodophiala bifida es una especie bulbosa nativa de Argentina, Brasil, Paraguay y Uruguay. El tamaño y color de sus flores la hacen muy atractiva para el cultivo ornamental. El desarrollo de protocolos de domesticación y mejoramiento genético son esenciales para poder proponerla como un nuevo cultivo, considerando que la industria florícola global requiere novedades. Como punto de partida, se hicieron estudios de compatibilidad y eficiencia reproductiva a través de la realización de cruzamientos controlados considerando fenotipos de flores de distintos colores. Tanto la autopolinización como la polinización cruzada produjeron frutos por lo que se comprobó un sistema reproductivo mixto en R. bifida. La eficiencia reproductiva fue significativamente mayor en la polinización cruzada que en la autopolinización siendo 49.6 y 19 respectivamente, para las flores rojas, genotipo más representativo de la población. No se observó fructificación en flores emasculadas sin polinizar por lo que se descartó la apomixis autónoma. Los cruzamientos entre fenotipos produjeron frutos excepto para el caso de cruzamientos entre fenotipos de flores rosas por fucsias.
