Agro-morphological characterization of sorghum accessions in Kibos 2022
Sorghum is an important dryland crop and plays a great role in improving food security in many regions in sub-Saharan Africa. The Genetic Resources Research Institute, Kenya holds a large sorghum diversity, including the duplicate collection of African sorghum genetic resources. Agro-morphological characterization was conducted for a total of 193 sorghum accessions in 2022. The experiment was conducted in Kibos, Kisumu County, Kenya. It was laid out in a 16 x 11 alpha lattice deign replicated 3 times. Characterization was conducted using IBPGR descriptors.
