The study was conducted to evaluate the performance of ten soybean genotypes in Southern Guinea Savanna of Nigeria. The experiments were conducted in three locations across the Southern Guinea Savanna of Nigeria during the 2021 cropping season. In each location, the experiments were laid out in Randomized Complete Block Design (RCBD) with three replications. Data were collected on plant height, number of leaves, growth and yield parameters and analyzed using Analysis of Variance (ANOVA) and means were separated using Duncan Multiple Range Test (DMRT). The results revealed that five genotypes (NCRI-SOY AC 18, NCRI-SOY AC 17, NCRI-SOY AC 69, NCRI-SOY AC 77, NCRI-SOY AC 73) were outstanding in yield across the three locations. Therefore, only five genotypes were stable in high yield. These five genotypes are recommended as donor parents in breeding of soybean varieties with both stabilities in high yield across environments. Also, the five genotypes are recommended for large scale soybean production in order to ensure adequate production and food security.
