Abstract
An experimental trail was conducted to differentiate the effect of sodium azide on yield and its attributes of chickpea. Overnight pre-soaked fresh seeds of ADBG-1, ICC-3020, ICCV-15112 genotypes were treated with various treatments of sodium azide (0.01%, 0.02%, 0.04%, 0.06%, 0.08% & control) for 06 hrs for the purpose of induction of mutation. The effect of sodium azide with unlike concentrations on yield and its attributing characters were studied in M1 generation of chickpea. Both laboratory readings and quantitative traits were recorded during experimentation. From the result, it was observed that all the laboratory readings exhibited reduction in their values upon increasing the concentrations of mutagen when compared to the control which was not treated. Whereas the efficacy of sodium azide on the average mean performance of quantitative traits on 03 chickpea genotypes exhibited that ICCV-15112 (0.04% SA) had higher seed yield and their attributing traits are Plant height, no. of secondary branches, biological yield and seed index.
