Abstract

We initiated a modest research effort on breeding alfalfa (Medicago sativa L.) for increased N2 fixation in 1974. This project became the first concentrated effort in the U. S. to breed a forage legume for increased N2 fixation. Now six years later we are taking this opportunity to look at the project in retrospect and to examine both the successes and the problems that we have encountered. Hopefully our experiences will be useful in projecting future advances and in suggesting methodologies and philosophies that can be utilized in other breeding programs for N2 fixation.
