摘　　要：Sorghum is a versatile and resilient crop that’s been cultivated for thousands of years. It is known for its ability to thrive in hot, dry conditions and withstand periods of drought, making it an important food source in many parts of the world. The objective of this study was to evaluate the adaptability and phenotypic description of introduced sorghum varieties in the North West region of Cameroon. The experiment was conducted in 2024 at the experimental farm of the University of Bamenda and was laid down in a Randomized Complete Block Design (RCBD) with four replications. The treatments were five introduced varieties from Mali and two varieties collected from the Northern region of Cameroon. The descriptive analysis revealed the morphological variation among the varieties on the stem, leaves and panicles of the plant. The analysis of growth and yield parameters revealed significant variation among the traits estimated. The highest emergence percentage was (96.62%) recorded by Wassanio, highest plant height (185.7 cm) recorded by Doussousouma-Nio, highest number of leaves (14) given by White sorghum, highest leaves length (95.37 cm) obtained by white sorghum, highest number of tillers (0.625) expressed by Grinkan, highest plant circumference (9.65) given by white sorghum. Additionally, the top 3 high-yielding introduced sorghum varieties were Tiandougou Coura (10.35 t/ha), Wassanio (9.9 t/ha) and Doussousouma-Nio (8.4 t/ha). These introduced varieties could be recommended for multi trials evaluation and release process in the North West Region of the country. Whereas, the white sorghum collected from the Northern region of the country was not adapted to the North West region.Sorghum is a versatile and resilient crop that’s been cultivated for thousands of years.
