Interest in the possibilities of developing better varieties of grasses has increased with the greater use of forage crops in agricultural systems, now commonly referred to as grassland farming. Forage grasses are now considered crops as part of the total farm enterprise. The general objective in forage grass improvement can be described as a search for the superior parents and populations of adapted productive varieties.

The objectives of this paper are to bring together ideas on methods of improvement of cross-pollinated grasses currently being used in the program at the Nebraska Experiment Station and to supplement these with ideas from other workers.

Results of the study showed when sufficient additive genetic variation is present within a species, further progress by selection may be accomplished. Desirable combinations of characters were obtained from which superior varieties could be developed in an improvement program.
