Jawaphool is a very popular traditional short grain aromatic variety of Chhattisgarh. Inspite of its premium gain quality it is very tall and having very late maturity. Due to tall stature this variety is prone to lodging which causes heavy reduction in yield. Physical mutagen (Gamma rays) is successfully utilized to develop the some promising Jawaphool mutants of traditional Jawaphool with reduced plant height, number of effective tillers per plant, earliness and higher grain yield and clustered panicle with red kernel colour. Frequencies of viable mutants with economically important characters were observed particularly for the dose of 300Gy in M2. This dose is also most desirable in inducing viable mutants in Jawaphool with semi tall stature and mid late to late maturity. Total 05 types of desirable mutants were selected and further advanced from M3 to M6 generations upto homozygosity. The frequency of different mutants over genotypes were observed as 04 are semi-tall ( 15 to 20% reduction in plant height) with mid late maturity and high grain yield and 01 are tall with late maturity, increased effective tiller, fertile spikelet’s per panicle , clustered panicle with red kernels and about 15 to 20% higher grain yield as compared to traditional Jawaphool variety.
