Abstract
The present investigation was devised to observe different doses of chemical and physical mutagen on the germination and survival percentage of okra variety Arka Nikita. Seeds of okra variety Arka Nikita were treated with different doses of gamma rays and EMS. The experiment was laid out in Randomized Complete Block Design (RCBD) with thirteen treatments and three replications. It was clearly observed that germination and survival percentage decreased with increase in doses of gamma rays and EMS. Results revealed that among different treatments, treatment T1 (Control) recorded maximum germination (85) and survival per cent (98.82) and observed dose-dependent reduction in biological factors such as germination and survival, the LD50 values for gamma rays and EMS were 0.4% and 60 kR, respectively.
