Comparative Mutagenic Effectiveness and Efficiency of Gamma Rays and Sodium Azide in Inducing Chlorophyll and Morphological Mutants of Cowpea.

ABSTRACT: Mutagenic effectiveness and efficiency are the most important factors determining the success of mutation breeding, a coherent tool for quickly enhancing genetic diversity in crops. However, conclusive evidence of using an effective and efficient dose of gamma (γ) rays and sodium azide (SA) for genetic improvement is scant. The present study assesses genetic diversity in M₂ mutants of cowpea and evaluates mutagenic effectiveness and efficiency of the single and combination doses of γ rays and SA. In M₀ generation, 7200 M₁ seeds obtained by SA treatment (0.01-0.1%) and γ irradiation (100-1000 Gy) at a dose rate of 11.58 Gy/min were sown to raise M₁ generation. A total of 57,620 M₂ seeds were generated from the M₁ generation o
