[Study on selective breeding of medicinal Chrysanthemum morifolium].
OBJECTIVE
To investigate botanical characters and yield of four cultivars of Chrysanthemum morifolium for further study on their genetic diversity and selective breeding.


METHODS
The characters were observed and yield was investigated by field randomized block and analysis of variance.


CONCLUSIONS
The botanical characters are difference among four cultivars; the amount of single flower head is the main factor influencing on the output of Chrysanthemum morifolium (r = 0.925); the yield of "Hongxinju" and "Xiaobaiju" are remarkably higher than that of "Dabaiju" and "Changbanju".
