Description Grain protein content varied from 6.8% to 19.6% in eight sorghum cultivars comprising land races,
hybrids, and local cultivars. Amino acid contents and distribution of Landry and Moreaux protein
fractions in grains were studied. Two Ethiopian land races had higher concentrations of lysine and
threonine, as well as cystine, isoleucine, and tyrosine. Fraction I, comprising albumin-globulin including
non-protein nitrogen, and fraction V (glutelin) together constituted about 41-55% of the protein
in the eight sorghum cultivars. Variation in fraction II (prolamin) and fraction III (cross-linked prolamin)
contents was observed among the cultivars. To elucidate the pattern of synthesis of protein
fractions in grain, studies were made at different grain maturity periods, using one cultivar. Fraction
I synthesis was initiated at 7 days after anthesis. Prolamin increased from 14 to 28 days and declined
toward maturity. Glutelin did not change beyond 14 days after anthesis until maturity
