| Summary: | AbstractAn experiment was conducted both under field conditions (Haramaya, Babile, and Hirna) and in the laboratory during the 2018 main crop season to analyze the impact of genotype by location based on seed yield and seed quality in Common Bean varieties. Thirteen varieties of common bean were tested at three locations in a randomized complete block design with three replications under field conditions while, for seed quality traits, they were tested at a standard seed testing laboratory in a completely randomized design with four replications. Analysis of variance was computed using GenStat statistical software version 16th. Accordingly, grain yield from Ayenew (5545.82 kg ha−1), and Gofta (5147.03 kg ha−1) genotypes was greater than other genotypes, respectively. The maximum grain yield was obtained in the Hirna location (6040.26 kg ha−1) due to its wide potential. However, location Haramaya was a representative and suitable site for the production of good quality seeds compared to other locations. The varieties Ayenew, Babile, Tinike, and Hundane yielded above the grand mean and also met the minimum (85%) national standard for germination of a common bean seed. Thus, it is better if farmers grow these high-yielding varieties with better standard seed germination to produce high-quality seed.
