Correlation and Path analysis were deployed to study Association of yield with some characters in fonio. AMMI model and GGE were in combination used to analyses stability and adaptability of fonio population in 9 locations across Nigeria during the 2022 and 2023 growing seasons. Twelve genotypes and a local check were involved, and the experiment was designed in a Randomized Complete Block, having 3 replications. Planting distance of 20cm x20cm on a plot of 3m x 4m was maintained. Sufficient variability was observed in the population. Plant height, spike length, panicle length and number of spikes per plant showed positive phenotypic correlations (0.989, 0.973, 0.977, 0.991 respectively) and genotypic correlations (0.991, 0.974, 0.98, 0.993 respectively) with grain yield, also indicating the traits were genetically determined. The genotype IBPL05-19-03 was consistent in high yields across the locations, indicating broad environmental adaptability and may be advanced in areas where environmental conditions are varied. Also, less adaptable genotype IBPL04-06-04 is recommended for specific micro-environments. Genotypes IBPL02-12-01, IBPL04-15-08, IBPL05-19-03, IBPL02-04-02 and IBPL05-07-09 showed stability and general adaptability to different environments due to their slope values being close to 1. Based on the traits-relationship analysis, breeding efforts that focus on improving plant height, panicle length, and more tillers are likely to lead to significant yield improvements in fonio. Integrating AMMI and GGE models in analyzing fonio lines provides a balanced statistical outcome giving applicable and informed decision for selection and development of genotypes that are high-yielding and stable across diverse environments.
