Abstract
Polyloidy was induced in the ornamental plant, Tagetus erecta (n=12) using 0.15 and 0.20 percent colchicine solution. Cytomorphological analysis of the colchiploids and diploid controls was made. It is seen that colchiploidy has effected significant enhancement of size of the capitulum and reduction in height of the plant. Both these characters add to the ornamental value of the plant.
