Chromosome pairing in the diploid hybrids Avena longiglumis Dur. × A. canariensis Baum, Rajhathy, et Sampson, A. strigosa Schreb. × A. canariensis, and A. damascena Rajhathy et Baum × A. strigosa is described in relation to the genomic affinities between them. The cytological data complete the picture of chromosome pairing between the A and modified A genome taxa and are compared with some previously reported Avena hybrids.Key words: Avena, hybrids interspecific, chromosome pairing, phylogeny.
