Hybrid plants were obtained in an intergeneric cross between Taenìatherum caputmedusae (2n = 2x = 14) and Triticum aestívum (2n = 6x = 42). The chromosome number was as expected 2n = 28. Morphologically the offspring looked like Triticum aestívum . Analysis of meiotic metaphase I showed an unexpected high number of bi‐ and trivalents which is ascribed to homoeologous pairing of chromosomes from T. aestivum . It is concluded that the genome of Taeniatherum has effects on the pairing regulation system present in T. aestívum .
