GAMMA RADIATION AND EMS TREATMENT OF BLACK CUMIN CULTIVARS FOR MUTATIONAL BIOASSAYS

Published on

Ten different types of chIorophyU mutations were induced in two cuItivars of black cumin
(Nigella sativa L.) after gamma irradiation and EMS treatment. Mutation frequency was
proportional to dose for gamma rays, but not for EMS. Higher doses of gamma rays and
lower concentration/duration of EMS were most efficient. Difference in the response of
both cuItivars due to mutagenic treatment indicate variation in the genetic architecture of
the two cultivars. Origin and use of black cumin cultivars for mutagen bioassays studies
are discussed.
