H.R. BUGHIO, I.A. ODHANO, M.A. ASAD AND M.S. BUGHIO

Abstract: A high yielding rice mutant variety Mehak has been developed from a fine aromatic variety Basmati-370, through gamma rays (150 Gy). The mutant variety Mehak was found significantly better than its mother variety Basmati-370 in respect of yield and yield contributing traits. It has shown consistency in better paddy yield than all the mutant lines including its parent and local check in various micro, preliminary and advanced yield trials at Nuclear Institute of Agriculture, Tando Jam for three years. On the basis of three years yield it has shown 80% increase in paddy yield over its parent Basmati-370 and 40% yield increase than check variety Super Basmati. The mutant variety is also inherited with excellent aroma and other physico-chemical properties of check varieties Super Basmati and Basmati-2000.
