Karyotypes of metaphase chromosomes in diploid populations of Dendranthema zawadskii and related species (Asteraceae) from Korea: diversity and evolutionary implications
Although the Dendranthema zawadskii complex has been known to comprise a series of polyploids (4×, 6×, 8×), we found diploid individuals (with 2n=18) to occur in four populations of D. zawadskii var. latilobum in...
