Abstract
Algunos híbridos F1 entre tres especies del género Aegilops y diferentes cultivares de trigo hexaploide Triticum aestivum poseen cierta fertilidad por autofecundación, con un porcentaje medio de híbridos F1 con semillas F2 del 8,17%, 5,12% y 48,14% respectivamente para Aegilops biuncialis, Aegilops geniculata y Aegilops triuncialis. En las combinaciones Ae. triuncialis-trigo con el cultivar de trigo "Astral" se obtuvo una fertilidad mayor que en las otras combinaciones. Todas las semillas F2 que se estudiaron fueron anfiploides formados espontáneamente (2n=10x=70). Este estudio evidencia la formación espontánea de estos anfiploides entre estas tres especies de A...
