The physicochemical characteristics of two mutants developed at the Nuclear Institute of Agriculture and Biology, Faisalabad [Pakistan] were examined. DM 16-5-1 from Basmati 370 has significantly higher yield (29.16%) that its parent. FG6 from IR 6 has higher head rice recovery (8%) than its parent. No significant differences were found between parent and mutant for 100-grain weight, grain length, breadth, size and shape, elongation ratio, amylose content, and gelatinization temperature. However, the length to breadth ratio for both groups differed significantly. Chalkiness scores, protein content, and gel consistency tests also were significantly different. But gel consistency values can be taken as similar because they ranged from 41 to 60 mm. Cooked grain length of DM 16-5-1 was less than that of Basmati 370; in FG6, it was the same as IR6. Aroma was strong in Basmati 370 and moderately strong in DM 16-5-1. IR6 and FG6 had no aroma.
