Abstract
Biological effects of Propane sultone under varied conditions of treatment such as presoaking, post washing, redrying and storage were studied in barley. A higher mutation frequency of mutagenic effectiveness and mutagenic efficency was observed in treatments involving presoaking and post washing for 8-16 hrs. Redrying of mutagen treated seeds to 10 and 20% moisture content enhanced mutation frequency but not efficiency, while storage for 4 weeks potentiated both the mutation frequency and efficiency of PS mutagenesis.
