Abstract
Synopsis: Progenies of natural pentaploid reed canarygrass possessed from 28 to 56 chromosomes. Non‐reduction was presumably a factor in the origin of octoploids. Hexaploids, though less regular meiotically than normal tetraploids, were more regular and fertile than octoploids. Chromosome number was not significantly correlated with leaf width but was correlated with date of anthesis (r = 0.62**). Leaves of euploids tended to be darker green than those of aneuploids. Seeds of hexaploids and octoploids were generally heavier than tetraploid seeds.
