Diversity in nuclear DNA content among 1263 seedlings germinated from pooled samples of open-pollinated achenes collected in five mixed-ploidy populations, one reference diploid population (no. 858) and one reference tetraploid population (no. 299); the offspring was assigned either to one of five euploid cytotypes (2x, 3x, 4x, 5x, 6x), or to one of three arbitrarily set classes of putative aneuploids (delimited by the closest lower and higher euploid cytotype: 2x–3x, 3x–4x, 4x–5x)
