Genome characterization of a synthetic Triticum x Thinopyrum (Poaceae) amphiploid using in situ hybridization
“Trigopiros” derive from crosses between different species of Triticum L. and ThinopyrumLöve. These synthetic amphiploids are designed with the aim to obtain cereals similar to wheat but whichare perennial, resistant to diseases and to the salinity of the soils. Moreover, they allow the transfer oft...

Caracterización del genoma de un Triticum x Thinopyrum (Poaceae) sintético amfiploide utilizando hibridación in situ. Los “Trigopiros” derivan de cruzamientos entre diferentes especies deTriticum y Thinopyrum. El objetivo es obtener cereales con características similares al trigo, perennes,resistentes a enfermedades y a la salinidad de los suelos. Además estos híbridos sintéticos son útilespara transferir al trigo atributos agronómicos de Thinopyrum. “Trigopiro” Don Noé INTA, que se cultiva actualmente en Argentina, presenta rasgos agronómicos valiosos, así como un alto contenido deproteínas seminales. En el presente trabajo se confirmó que el número de cromosomas de “Trigopiro”Don Noé es 2n = 56. Técnicas de hibridación in situ (FISH-GISH) permitieron postular su composicióngenómica desconocida hasta el momento. Este híbrido artificial posee 14 cromosomas del genoma J deThinopyrum y 2 pares de cromosomas con posibles translocaciones entre Triticum y Thinopyrum. El restode los cromosomas pertenecen a los genomas A, B y D de Triticum.
