An attempt was made to study the quantity, nature and direction of induced micromutations for quantitative characters in wheat by seed aging. Range in the aged population was more altered than that of the unaged control for most of the characters. The mean value decreased significantly in the aged population as compared to the control for the plant height and number of nodes per plant, while a significant increase in mean value was observed for the number of tillers per plant, 100-grain wt, days to heading and plant yield. In the aged population, a significant increase in variance for all characters under study was noted. The coefficient of skewness was positive and significant for most of the characters. Positive and highly significant coefficients of kurtosis were observed for most of the characters. The scope of the seed aging in inducing variability was discussed.
