Abstract:
An intergeneric hybridization between
Ajania and
Chrysanthemum was produced by hand pollination in this study to introduce new germplasm into
Chrysanthemum gene pool. One intergeneric hybrid of
Ajania achilloides×
Chrysanthemum morifolium‘Beijin’ was identified by morphological characteristics comparison and cytological analysis including flow cytometry. The hybrid was identified by the characteristic with ray florets which were quite different from that of maternal parents. It was found that the hybrid was tetraploid while the parents were diploid and hexploid based on cytological studies. The intergeneric hybrid could be used as the bridge for breeding of drought-resistant chrysanthemums.
