Abstract:
The present investigation was carried out with an objective of assessing the response of two selected groundnut genotypes viz., ICGS-76 and Rajashree to different doses of sodium Azide (0.2%, 0.4% and 0.6%). The relative effectiveness and efficiency was assessed from the data on biological damage and frequency of chlorophyll and visible mutants in M2 generation. The mutagenic effectiveness and efficiency were found to be higher for lower and intermediate doses of mutagen in both varieties. Among the two varieties ICGS-76 was found to be more sensitive to mutagenic treatment than Rajashree variety.
