Abstract :
An investigation was carried out to induce
mutants in Gloriosa superba L. possessing high value alkaloid
viz., colchicine and colchicoside, used in the treatment of
gout, rheumatism and cancer. VM2 generation was raised
from EMS, DES and gamma ray treated VM1 tubers of
Glory lily. The mutants had apparent morphological changes
in plant height, number of leaves and flowers as well yield
characters. Five high yielding mutants viz., T8P2, T10P1, T10P4,
T7P3, T9P4 were subjected to colchicine estimation using High
Performance Liquid Chromotagrapy. These promising
mutants seemed to possess high colchicine content, than the
control. The maximum colchicine content of 0.707 per cent
was observed in 2.00 per cent EMS (T7P3), followed by 0.702
per cent in 1.00 per cent DES (T8P2). The obtained results
implicate that physical and chemical mutagens contribute to
variations in alkaloid content.
