A PREPONDERANCE of evidence indicates that commercial alfalfa, Medicago sativa L., is essentially an autotetraploid (7). Despite this fact, most quantitative genetic studies :in alfalfa have been analyzed as if alfalfa exhibited diploid inheritance. If quantitative genetic studies are to be of value to breeders in elucidating the type of gene action present in alfalfa, they should be analyzed assuming autotel:raploid inheritance. The objectives of the work reported in this paper were (a) to interpret mating designs practical for quantitative genetic studies in alfalfa in terms of autotetraploid inheritance and (b) to develop a useful procedure for estimating components of genetic variance in alfalfa.
