Genomic affinities between maize and Zea perennis using classical and molecular cytogenetic methods (GISH-FISH)

Mostrar todas las versiones(2)

In this study we have analysed and compared the genomic composition, meiotic behaviour, and meiotic affinities of Zea perennis and Zea mays ssp. mays. To do so we studied the parental taxa and the interspecific hybrid Zea perennis x Zea mays ssp. mays, using classical cytogenetic methods, as well as...
