Abstract
Artificial crosses between the Japanese, octoploid Chrysanthemum shiwogiku Kitamura and Chinese, hexaploid C. vestitum (both Asteraceae-Anthemideae) produced 48 hybrids out of 181 germinated plants grown up to the mature stage. The hybrids showed more or less intermediate in morphological character between the two parents and somewhat more close to C. vestitum in white-color ligule flowers inherited. The chromosome numbers in 19 out of 48 hybrids studied varied from 2n=63 to 81 with various aneuploids and some individuals showed very small-sized chromosomes perhaps due to B-chromosomes of which undetected parentage had produced. The hybrid plants might be able to produce back-cross progenies after hybridization with C. vestitum as a paternal parents, as well as could hybridize with sister plants of the F 1 hybrids as ovule and pollen donors.
