Abstract A development of early‐maturing sorghum varieties is the foremost strategy in moisture‐deficit areas so as to alleviate rain fed–dependent agriculture. An experiment was conducted with the objective of identifying relatively high‐yielding and adaptable sorghum variety for the moisture‐deficit areas of the Amhara region. Sixteen sorghum genotypes, including appropriate checks, were evaluated at seven different environments of six locations, namely, Kobo, Jari, Chefa, Aybira, Gonder, and Shewarobit, in 2021–2023 under rainfed condition. The experiment was conducted using a randomized complete block design with three replications. The combined analysis of variance over locations and years revealed highly significant difference ( p < 0.01) among genotypes for all measured traits. Genotype (G) by location (L) was highly significant ( p < 0.01) for all traits. The highest grain yield (5.247 ton ha −1 ) was obtained from genotype G8 (Raya × Jamiyo‐5‐7), while that of standard and local checks was 3.99 and 3.76 ton ha −1 , respectively. The yield advantage of the candidate genotype, Raya × Jamiyo‐5‐7, over the standard and local check were 31.24% and 39.47%, respectively. As a result, Raya × Jamiyo‐5‐7 was selected, verified, and officially released in 2025 for its early maturing and high yield, given the name Sirinka‐1, and recommended for production in moisture‐deficit areas of the Amhara region and similar agroecologies of the country.
