Sorghum Characterization at Samanga Short Rain 2023
This dataset contains agro-morphological characterization data for 101 sorghum (Sorghum bicolor (L.) Moench) accessions conserved at the Genetic Resources Research Institute (GeRRI), Kenya. The characterization was conducted during the 2023 short rain season at Samanga, Homabay County, Kenya. The trial was established using a Randomized Complete Block Design (RCBD) with three replications. Characterization was undertaken using standardized Bioversity International sorghum descriptors, and data were collected on a range of qualitative and quantitative traits including phenological development, plant architecture, panicle characteristics, grain traits, and agronomic performance. The field site at Samanga is located at Latitude 0°27′S, Longitude 34°33′E, and an altitude of 1,150 m above sea level. Samanga represents a relatively warm sorghum-growing environment within the Lake Victoria Basin, characterized by annual rainfall of approximately 1,100–1,400 mm and temperatures ranging from 23–28°C.
