Abstract
Two varieties, viz., M35-1 and GM2-3-1, of Jowar (Sorghum vulgare) were irradiated with 20 kr, 30 kr and 40 kr dosage of gamma rays. Radio-sensitivity in M1 generation revealed that germination, seedling growth, survival and pollen sterility were affected to a considerable extent, but no detectable chromosomal changes were noticed in meiotic metaphase. In the M2 generation, a wide spectrum as well as a high frequency of both chlorophyll and viable mutations were recorded. A high frequency of albino mutants were observed in GM2-3-1. whereas in M35-1 the frequency of chlorina, xantha and tigrina was more. M35-1 appears to be highly mutable compared to GM2-3-1. In addition to many agronomic types of viable mutations, drought resistant types have been recorded.
