Abstract

Eighteen inbred lines from the world sorghum collection and RS610 were tested with three levels of nitrogen fertilization. The same 18 inbred lines were grown under high fertility conditions. Significant differences among lines existed for height, lodging, maturity, weight of 100 seeds, grain weight per panicle, protein, lysine in protein, and protein ✕ lysine within each test. Nitrogen fertilization affected the protein production significantly, but variation among lines was much greater. Genotypic range for protein production was 11.7 to 16.3%. Lysine as percent of protein was not affected significantly by nitrogen fertilization, but genotypes ranged from 1.64 to 2.52%. A comparison of a very high fertility treatment with three nitrogen fertilization levels showed that there were significant differences among fertility levels and among genotypes for grain weight per panicle, protein, lysine in protein, and protein ✕ lysine. Protein was 0.6% higher for high fertility while lysine was 0.47% lower, grain weight per panicle was 10.7 g lower, and protein ✕ lysine was 5.68 units lower for this location. There was a significant interaction between genotype and location for lysine, protein ✕ lysine, and grain weight per panicle, but not for protein production.
