Abstract

Six accessions of Sorghum bicolor, two of S. almum and one of S. sudanense were grown at six sites in a single crop year. Evaluations were based on field yields, agronomic characteristics, and physical and chemical composition. Growing conditions caused considerable variation. The best productivity for several accessions exceeded 10 tons per acre for whole stalks and 6 tons per acre for culms. The mean content (for three sites) of crude cellulose in culms ranged from 40.9 to 53.8% and of alpha -cellulose from 25.7 to 34.7%; the amount of pith ranged from 6.1 to 15.2%. Ash content in culms was 3% or less, compared with 7% or more in leaves. The late-maturing accessions PI229837 and PI229847 were consistently good yielders, but were chemically inferior to PI177549 and PI190579. The composition of PI177549 was the most favourable, with a high proportion of culms to leaves and with a crude-cellulose content of 58.4% in the culms (Georgia). In Iowa, the content of crude cellulose in culms of PI229837 was equivalent to 3.40 tons per acre, and that of alpha -cellulose to 2.31 tons per acre. Accessions meriting further consideration were PI177549 (broom corn), PI229837 and PI229847 (Kafir types), and PI190579 (S. almum)
