Resumo: 	Chromosome elimination in interspecific hybrids is a powerful tool in breeding programs. Of 12 Brazilian oat varieties recommended for cultivation in southern Brazil, one variety, UFRGS 15, presented a new type of chromosome elimination never described in any other species. Chromosomes that produced micronuclei during meiosis were eliminated from microspores as microcytes. The micronucleus reached the microspore wall and formed a kind of bud, separated from the microspore. The eliminated microcytes gave origin to small and sterile pollen grains. The possible applications of this finding for oat breeding are discussed.
