Background: Sorghum [Sorghum bicolor (L). Moench] is a climate-resilient cereal crop that thrives in harsh environments where other cereal crops cannot perform well. In Ethiopia, sorghum can grow in a wide range of altitudes ranging from lowlands to highlands. It is currently serving as an important food security crop, and it is used for food, animal feed, and its stalks for constructing rural hut houses. Despite such merits, the production and productivity of the crop is hampered by a lack of acceptable sorghum varieties meeting the requirements of farmers and the market. Objective: The study aimed to identify and develop high-yielding, stable, and disease-tolerant sorghum variety with farmer and market-preferred seed color for wider production and use. Materials and Methods: Twenty sorghum genotypes including standard check variety (Bonsa) were evaluated using Randomized Complete Block Design (RCBD) with three replications at Bako, Gute, and Bilo areas during 2017-2019 under rain-fed conditions. All agronomic practices were applied per recommendation. Data were collected on phenological, agronomic, and yield traits, then subjected to analysis of variance. Results: The results of the study have revealed that there were significant variations among the tested sorghum genotypes, with [ETSL 101259 (Acc. 200161)] named "Jabaa" being the most superior to the other genotypes with a mean grain yield of 3.9 t ha-1 and other merits. Additive Main effect and Multiplicative Interaction (AMMI) and Genotype and Genotype by Environment (GGE) bi-plot also indicated that this genotype [ETSL101259 (Acc. 200161)] was found to be the most stable and high-yielding among the tested genotypes. In addition, Jabaa is a white-seeded variety exhibiting disease tolerance and meeting the criteria for farmers' preference and market demand. Furthermore, "Jabaa" showed about a 44.4% yield advantage over the best standard check variety, Bonsa. Conclusion: The results of the present study revealed that, among the tested genotypes, Jabaa [ETSL101259 (Acc. 200161)] was found to be a high yielder, stable and tolerant to sorghum foliar and panicle diseases, and resistant to bird attacks and lodging. Furthermore, the variety's white grain color has a high demand in the market and is an additional merit. Having such merits, the Ethiopian Variety Release Standing Committee has officially approved [ETSL101259 (Acc. 200161)] release of the new variety with the breeder name "Jabaa" for wider cultivation and use in Ethiopia.
