The study was u der taken on genetic variability in dahlia genotypes for vegetative, floral and tubers characters of Dahlia (Dahlia variabilis) for two successive years. Forty varieties viz.

A wide range of variation in the mean performance of different parameters in varieties was observed for all the traits taken in the present investigations Traits like plant height, number of branches/plant number of flowers/plant, number of days required for bud emergence and its maturity, length of flower bud, number of flowers/plant, diameter of flower, number and weight of tuber etc. showed relatively larger variations, compared to other during both years of investigations.
