• Autotriploid of Chrysanthemum coronarium, a winter ornamental with considerable structural heterozygosity, was obtained through open pollination of induced autotetraploid. The triploid with radiate yellow capitula was luxuriant with large sized capitula which are fewer in number. Besides trivalents, it has multiple associations constituted as a consequence of structural heterozygosity for reciprocal translocations. In spite of large chromosome size and high chiasma frequency in the diploid, only 55% chromosomes are involved in multivalents. Of the trivalents, 'chain' type is the most common. In spite of 56% pollen fertility, the triploid completely lacks achene formation. Maintenance of triploid was not possible for the species lacks vegetative multiplication.
