Genotype x environment interaction was evaluated under six environments during 2017 to 2019 cropping season in the highlands of bale, Southeastern Ethiopia for grain yield of fifteen promising lentil genotypes promoted from the previous trials. Randomized Complete Block Design with four replications was used. The ANOVA revealed significant variation of grain yield for genotypes, environments, and genotypes by environment interaction. The explained percentage of grain yield by the environment, genotype, and genotype-environment interaction was 47.64, 25.47, and 26.89 respectively. In Additive Main Effect and Multiplicative Interaction (AMMI) analysis, the first two Principal components revealed more than 73% of the variability for the yield which indicates that G and GE together accounted for more than 25 percent of the total variability. The results finally indicated that AMMI stability value, GSI, and AMMI biplot are informative methods to explore stability and their by in subsequent variety recommendations. Based on AMMI Stability Value (ASV), G13, G5, G12, G1, and G15 showed the least ASV and were found to be more stable whereas G10, G7 G9 G8, and G14 have the second lower ASV and showed moderate stability. Based on Genotypes Selection Index (GSI), G5, G13, and G15 showed the lowest GSI whereas G10, G1, G4, G11, and G15 showed the second-lowest GSI. However, G4 and G10 gave grain yield higher than the checks, with moderate stability. Therefore, these two genotypes were identified as candidate genotypes to be verified for possible releases for the highlands of Bale, Southeastern Ethiopia, and similar agro-ecologies.

The name Milkesa was given to Large-red seed Food Type Common Bean (Phaseolus vulgaris) variety with the pedigree of DAB-523. The objective of this study was to register stable high yielding and disease resistant/tolerant common bean variety for midlands areas of Bale, East bale and other similar agro-ecologies in the country. Total of sixteen Large-red Seed Common Bean genotypes including the standard check "Melka dima and Red kidney" were evaluated across two locations (Goro and Ginner) for three years (2015 to 2017). One promising genotype, "DAB-523" were selected and promoted to variety verification trail with the standard check during the 2020/21 cropping season. The national variety release technical committee evaluated the candidate varieties both at Goro and Ginner. Milkesa is characterized by large-seeded with red grain color and gave high seed yield (1626kg ha -1 ) and stable performance across years and locations. It has about 10.03% yield advantage over the best standard check variety, "Melka dima". The variety is also resistant/ Tolerant level of reactions to Alternaria Leaf Spot, Common Bacteria Blight and Rust. Milkesa is released for the Midland Areas of Bale, East Bale, and similar agro-ecologies. Therefore, farmers could be cultivated Milkesa for increasing productivity of the crop with its full recommended packages.

The presence of significant G*E for quantitative traits such as yield can seriously limit the feasibility of selecting superior genotypes. Thus, the purpose of this study was to investigate grain yield stability and genotype X environment interaction for fifteen Ethiopian Mustard genotypes (Brassica carinata A. Braun) conducted in the highlands of Bale, Southeastern Ethiopia for three consecutive years (2018 to 2020) at two locations, Sinana and Agarfa. Randomized Complete Block Design with four replications was used. The combined analysis of variance for grain yield indicated highly significant interaction (P<0.01%) for genotypes, genotype X environment interaction, and environment. The analysis of variance for AMMI for grain yield revealed highly significant interaction for genotypes, genotypes X environment interaction, and environment. It was observed that 44.84% of the variation in grain yield was accounted by environment, 37.54% for genotypes by environments, and, 17.62% was for genotypes. The first and the second IPCA components with degree freedom of 34 was accounted for 67.64% of the interaction effect and revealed the two models were fit. Genotype G12, G11, G8, and G1 showed the lowest AMMI Stability Value (ASV) indicating stability. Furthermore, Genotypes G11, G12, G5, and G8 have the lowest GSI value indicating high stability. However, out of these genotypes, G11 showed a high mean grain yield with a yield advantage of 25.8% and showed the lowest GSI value compared to overall genotypes and the checks used in the study. Therefore, G11 was identified as a candidate genotype to be verified in the coming main season of 2022/23 for possible release for the highlands of bale zone, Southeastern Ethiopia, and similar agro-ecologies.

Ethiopia has suitable environmental condition for common bean production. However, the productivity of common bean is very low as compared with world average due to lack of stable, high yielding, and disease resistant genotypes. Therefore, the objective of this study was to register stable high yielding and disease resistant/tolerant common bean variety for midlands areas of Bale and other similar agro-ecologies in the country. The experiment was carried out at two locations from 2015 to 2017 main cropping season using 15 genotypes including standard checks. Eventually, two promising genotypes, "SCR-28 and SCR-8" were selected and promoted to variety verification trail with the standard check ''SCR 1 and Nasir" during the 2020/21 cropping season. The National Variety Release Technical Committee evaluated the two candidate varieties at Goro and Ginner on research stations and farmers' fields. Among the two evaluated varieties, SRC-28, 'Hora', is well adapted to altitudes ranging between 1600 and 1950 meters above sea level and gave high seed yield (1587 kg ha -1 ) and stable performance across years and locations. It has about 29.3% yield advantage over the standard check variety, "Nasir". Hora is also resistant/ Tolerant level of reactions to Alternaria Leaf Spot, Common Bacteria Blight and Rust. Hence, Hora is released for Midland Areas of Bale, East Bale and similar agro-ecologies for its stable, high grain yield and resistant to major diseases. Therefore, farmers could be cultivated Hora for increasing productivity of the crop with its full recommended packages.
