Sorghum [Sorghum bicolor (L.) Moench] is a cereal crop grown mainly for food, feed, fodder, and fuel. Fifty sorghum accessions collected from ten southern States in Nigeria were characterized using qualitative and quantitative markers to identify the extent of variability among the accessions. The experiment was laid in a randomized complete block design with three replicates at FUTA (2019 planting season), FCAI (2018 and 2019 planting seasons) and Ogbomoso ADP (2018 and 2019 planting seasons). Qualitative and quantitative data were collected on 22 morphological traits. Results from the qualitative markers depicted that more than half of the accessions had 75% grain coverage, dull green midrib (52%), medium bloomy waxy bloom (68%), very loose dropping panicle (44%), exerted panicle (76%), good threshability (50%), black glume colour (46%), buff grain colour (48%), intermediate senescence (54%) and low lodging (76%). Analysis of variance for the quantitative traits showed the existence of significant variation among the traits for all the environments, genotype and GEI at p≤0.01 except for leaf length and leaf width, which were not significant for genotype and genotype*environment, respectively. Accessions RI-17-01, EN-17-03, OS-17-05, AB-17-01, EN-17-01, OG-17-02, OY-17-03, EB-17-01 and AK-17-01, which had the highest mean for the eleven quantitative traits, can be selected for a sorghum improvement programme in southern Nigeria.
