Abstract
Relationship between 1, 3-Propane sultone (PS) induced toxicity measured as percentage seed lethality, seedling growth injury, spike sterility, survival in M1 and its mutagenic response was studied. Higher mutagenic response was obtained at concentrations of PS that caused 30-60% seed lethality, seedling growth injury and spike sterility. Further increase in toxicity as a consequence of rise in concentration had adverse effect on mutability of PS.
