Abstract

Sunflower [Helianthus annus L.] belongs to family composite (Asteraceae). In the present study experimental seeds of two sunflower cultivars namely ‘Bhanu’ and ‘SS­56’ treated with various concentration of chemical mutagens [EMS and SA] and physical mutagen (Gamma rays). Effect of these mutagens on pollen sterility were studied in M 1 generation. The maximum pollen sterility in the variety of Bhanu (71.42%) could be observing in gamma ray 10 kR while variety of SS-­56 (42.32%) observed in EMS 0.10 %. The induced mutation plays an important role in crop improvement, either through physical and chemical mutagens.
