Abstract: Twenty-one stable wheat mutant lines along with four check varieties viz., Sarsabz, Kiran-95, T.J.83 and Khirman were evaluated under normal and late sowing dates. The observations were recorded on phenological, morphological and meteorological parameters. Higher yield and improvement in various yield components were recorded at normal sowing as compared to late sowing. Six mutant lines showed superiority in yield than check varieties at normal sowings while three mutants produced more yield than check varieties except Sarsabz at late sowings. At normal sowing eleven mutant lines matured earlier than all check varieties including short duration variety T.J-83 whereas two mutant lines were earlier than Sarsabz and Kiran-95 and thirteen than T.J-83 and Khirman.
