VARIATION OF FRACTION 1 PROTEIN CONTENT IN ALFALFA

Abstract
An alfalfa population consisting of plants of Medicago sativa L., M. media Pers., and M. falcata L. varied significantly for Fraction 1 (18S) protein content. M. falcata plants, as a group, contained about half as much Fraction 1 protein as M. sativa plants while M. media plants tended to fall between these two in Fraction 1 protein content. It is suggested that M. falcata may be a source of low Fraction 1 protein content. There was no appreciable association between Fraction 1 protein content and other chemical constituents.
