This study delves into the genetic diversity of sorghum (Sorghum bicolor) worldwide, with a focus on analyzing its significance in crop improvement and addressing climate change. Sorghum exhibits rich genetic variation in different regions. Studies from countries such as Ethiopia, Niger, and Senegal have shown that local varieties carry unique genes that are of great value for cultivating new sorghum varieties that can adapt to harsh climates.Scientists have utilized tools such as genotyping sequencing (GBS), microsatellite markers, and single nucleotide polymorphisms (SNPs) to identify multiple important gene regions associated with traits such as plant height, flowering time, and drought resistance. Case studies from Africa show that Ethiopian sorghum has a rich gene pool, while West African sorghum exhibits strong adaptability to high temperatures and drought. The research results provide important ideas for sorghum breeding.
