Summary
Lines derived from three cross populations of spring barley were used to investigate whether grain yield can be improved by selection for earliness and number of ears/m2. Time of booting was considered to be indicative for earliness. Selection for early versus late booting was successful in all three populations. Selection for high and low numbers of ears/m2 was successful in only two populations. However, the effects of selection for these traits on grain yield were insignificant.
