Description
Acid soils and their related toxicities are found in every continent of the world. Since liming and fertilization rarely overcome subsoil acidity, poor rooting usually results when growing sensitive legumes such as alfalfa ( Medicago sativa L.). Subsoil liming increased alfalfa yield 46 % over conventionally limed controls indicating deeper rooting achieved through an ability to overcome subsoil toxicity significantly enhanced stand life and productivity (Bouton et al., 1986). If acid soil tolerance could be incorporated into new multiple-pest resistant cul ti vars without loss of their desirable traits, farmers may realize the benefits of any new alfalfa cultivar. The purpose of this investigation therefore was to determine the success of recurrent selection for developing acid soil tolerant alfalfa by monitoring changes in forage yield and disease resistance as well as acid soil tolerance.
