Abstract: Fast neutrons (10 and 25 Gy) and gamma rays (150, 200, 250 and 300 Gy) were used to induce desirable mutations with regard to yield and quality characteristics in IR6 (non-aromatic) and Basmati-370, Jajai-77 and Sonar Sugdasi (aromatic) varieties of indica rice. Six stable mutants of non-aromatic varieties viz., IR6-252, IR6-25-1, IR6-30-1, IR6-1.0-2, IR6-1.5-2 and IR6-2.5-2 and six mutants of aromatic varieties viz., Basmati-2.5, Basmati-15-14, Basmati-20-1, Basmati-30-2, Jajai-77-2 and Sonahri Sugdasi-20-1 were evaluated in zonal trials over 9 different locations in the Province of Sindh and Balochistan. All the non-aromatic mutants except IR6-2.5-2 were significantly (P≤ 0.05) superior in yield to the parent IR6. The mutant IR6-252 had the highest paddy yield. Similarly, all the aromatic mutants except Basmati-2.5 were significantly (P≤ 0.05) superior to their respective parents and check variety. The mutant Basmati-20-1 had the highest paddy yield followed by mutant Basmati –15-14. All the mutants maintained their superiority in grain quality characters over their respective parents.
