Chrysanthemums. Maintaining varietal character


, : Chrysanthemums. Maintaining varietal character. Grower 89(14): 857, 859-860

Flowering response (number of short days to flowering) and flower quality were compared for clones of the year-round chrysanthemum cvs Heyday and Polaris. The clones were raised by meristem culture from apical and axillary buds of stock plants. With Heyday, at least 6 different clones could be recognised in material derived from a single shoot of one stock plant although they were apparently genetically similar. Similar but less marked clonal variation was observed with Polaris.
