Abstract

Some varieties of sorghum (Sorgum bicolor) available in the North of Cameroon have been characterized for to their ability to meet consumers and industries requirements. Local varieties of sorghum, namely ``Zouaye," ``Djigari," ``Damougari" have been compared to four selected varieties with good agronomic characteristics (S35, CS-210, CS-95, CS-54). Results indicate that the varieties CS-95, CS-54, and ``Madjeru" present very high percentages of cut brown grains with a variation from 48% to 87%. The variety ``Dmougari" seems harder than the others with a PSI of 19±2.6. Varieties CS-210 and CS-95 appear to be most tender with successive PSI of 11.8±5.21 and 12.2±1.2. All local varieties (Madjeru, Zouaye, Damougari, Djigari) have shown a 1000-kernel weight ranging between 21.9±2.6g and 25.5±1.5g, whereas selected varieties (S35, CS-210, CS-95, CS-54) present 1000-kernel weight binds between 15.43 ±2.5g and 19.31±5.21 g. The majority of the studied grains present an index of vitrosity between 1.6 and 4.85, except CS-210, Madjeru, Djigari which are semi-vitreous (with indices of vitrosity ranging between 3 and 4. Dihurin content of all varieties ranges from 108±15 to 225±23 (ppm). The colour of the grain shows that the improved varieties present yellow blades and yellow ivory colours, whereas the local varieties are brown and red.
