Induced mutagenesis in wheat varieties PBW-154 was studied during the Rabi season of 2011-12 at the Agriculture Research Farm, R.B.S. College, Bichpuri, Agra. The seed of wheat variety PBW-154 was subjected to different mutagens. There were seven treatments related with temperature. The treatments of 500C and 150C enhanced the germination percentage up to 100 and 99 percentage respectively as compared to 93 percentage in control and 0.3 percentage hydroxyl amine treatments. More or less similar effect of the treatments on other parameters viz. root length, shoot length & seedling vigour index was observed. Higher dose of hydroxyl amine was observed to be undesirable.The parameters of variability such as  range, mean and CV revealed highest (45-75) range for grains per spike and 100 grain weight (3.31-4.62g)), for  plant height the maximum values of 117.86 cm  was observed. The CV estimate was high (15.04 percent) for tillers per plant, where as it was lowest (2.77) for days to flowering. The estimates of GCV and PCV were highest for grain per spike and lowest GCV estimates for 100 seed weight. Macro mutations of economic and academic interest were also recovered in present study the recovery of bold shiny seeded mutant by the use of 15ºC temperature and high grain yielder mutants by the use of 15ºC temperature  note-worthy.
