A Comparison of Predicted with Realized Gain from Selection for Leafspot Resistance in Alfalfa1

M. W. Adams and G. Semeniuk2

Synopsis: It was predicted that a combination of family and individual selection for resistance to common leafspot in an alfalfa population would improve the mean score from 3.32 to 2.39. Actually, the new population resulting from intercrossing the selections measured 2.06. Additive genetic variance was virtually exhausted by one generation of selection.
