Chlorophyll and morphological mutants of Pearl millet (Pennisetum tphoides (Burn.) stapf. Var. CO(cu)⁹

Ambli K. and L. Mullainathan

Chlorophyll and morphological mutants play an important role to assess the dose/concentration of mutagens. Pennisetum typhoides variety CO (cu)9 were treated with Gamma rays and EMS. The seeds were treated with different concentration of gamma rays such as 10, 20, 30kR and 20, 30, 40mM of EMS. In the present investigation, three chlorophyll mutant and twenty morphological mutants were observed in M₂ generation. The mutants are Albino, Xantha, Viridis, Tall, Dwarf, Bushy, Brittle stalk, Barren stalk, Tillers, Narrow leaf, Lazy, Zebra striped, Brevis, Male sterile, Nana dwarf, Crinkly leaf, Brachytic, Early maturity plants, Late maturity plants, Long panicle, Small panicle, Bold seeded and Small seeded. EMS provided more number of chlorophyll and morphological mutants followed by gamma rays in the investigation.
