The effect of selection for lower ear height on yield in synthetic populations of maize

Two populations of maize [ Antigua 2D x (BIO x Bl4)] and F 5 [ Eto x CBC3]f 5 were used in a selection experiment conducted in Lafayette, Ind. in order to determine the effectiveness of 50% selection, pressure in lowering the ear height. These two populations were subjected to two cycles of selectio...
