Incidence of polygenic mutations follows a trend opposite to the previous selection history of the variety. In N.P. 876, which is a low tillering variety, the incidence of polygenic mutations is in a positive direction; in N.P. 863 which is a high tillering variety the mean is shifted in the negative direction; whereas in N.P. 870 an average tillering variety there is no change in the mean. The variance is increased in all the varieties in treated populations.
