Abstract

Mutagenic effectiveness and efficiency of γ-rays, EMS and NMU were studied in L. sativus. The order of the mutagens based on effectiveness measured by the frequency of mutations induced by unit dose of mutagen was: NMU>EMS> γ-rays. Efficiency of the mutagens as measured by the proportion of mutations in relation to undersirable effects in M1 was: γ-rays> EMS>NMU. Both mutagenic effectiveness and efficiency were higher at lower doses of the mutagens.
