Abstract
The present investigation was carried out to determine the mutagenic effect of Sodium Azide on morphological traits of Kadiri-6, Gujarat Gold, Haritha Andhra and Kadiri Amaravati (Arachis hypogaea L.) in M2 generation. Pre-soaked seeds were treated with different concentrations w/v (0.1, 0.15, 0.20, 0.40) of sodium azide for 17 hrs at room temperature. The experiment was carried out with four doses of mutagen (sodium azide) for four different varieties along with their respective controls in the Randomized block design with three replications. The observation of growth parameters of both M1 & M2 mutants of Kadiri-6, Gujarat gold, Haritha Andhra and Kadiri Amaravati showed a significant variation in different traits such as germination percentage, survival percentage, seedling height, days to maturity, days to flowering, number of sterile plants, plant height at maturity, number of pods per plant, sound mature kernels and kernel yield per plant. Most of the traits decreased with an increase in the concentration dosage of sodium azide. The result of the study shows that sodium azide majorly affected the above-mentioned traits, it has significant influence on all the traits under study.
