  • All the seeds taken from a fruiting specimen of Rorippa barbareaefolia (2n = 16) growing in the Yukon Territory produced plants with 24 somatic chromosomes. These plants were first-generation hybrids between R. barbareaefolia (2n = 16) and R. islandica (2n = 23). The female parent, R. barbareaefolia, was male sterile. Pairing configurations in pollen mother cells of these first generation hybrids suggested that the male parent, R. islandica, was autotetraploid.
