Abstract
A total of 200 finger millet genotypes, collected from various regions and altitudes in Ethiopia, along with some introductions from Eritrea, Zambia, and Zimbabwe, were planted alongside two improved varieties to evaluate genetic diversity for qualitative traits. This experiment, conducted using a 10 x 20 lattice design at Maiaini during the 2019 and 2020 cropping seasons, utilized descriptors from the International Plant Genetic Resource Institute (IPGRI). Observations indicated that traits such as non-seed persistence, erect ear shape, purple glume color, and black seed color were commonly found across all regions, altitude classes, and countries of origin. Shannon diversity analysis revealed high diversity indices for genotypes from Zambia and Zimbabwe (H’ = 0.90 ± 0.05), with Benishangul Gumuz exhibiting the highest regional diversity for seed pericarp persistence and glume color (H’ = 0.99). Significant differences (P ≤ 0.05) were found in seed pericarp persistence and highly significant differences (P ≤ 0.01) in seed color between countries, while other traits showed no significant differences. Regionally, seed color exhibited significant differences (P ≤ 0.05), with other traits showing non-significant variations. These findings emphasize the substantial genetic diversity in finger millet, the significance of farmer preferences, and the potential for further research and conservation. Understanding the geographical distribution of economically important traits and overall diversity is crucial for effectively utilizing these genetic resources to enhance productivity and environmental resilience in this vital crop..
