N1  - The authors acknowledge the technical staff of Debre-Zeit Agricultural Research Center for their support during data collection. This study was conducted jointly by Debre-Zeit Agricultural Research Center, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and The International Center for Agricultural Research in Dry Areas (ICARDA). Financial support coming through the Ethiopian Federal Ministry of Agriculture, CGIAR Research Program on Grain Legumes (CRP-GL) and Tropical Legumes Projects (TL2 and TL3) are hereby acknowledged.
N2  - This study was conducted to determine the interaction between chickpea genotypes with the environment (GxE) on the yield stability and adaptability of desi type chickpea genotypes (Cicer arietinum L.). Seventeen chickpea genotypes were evaluated for two cropping years (2012/2013 ? 2013/2014) at four locations i.e., eight environments (locations x years combination). Chickpea grain yield was significantly (p<0.01) affected by genotypes, the environments and GxE interaction, indicating that the varieties and the test environments were diverse. GxE was further partitioned by principal component axes. The first two principal components cumulatively explained 53.1% of the total variation, of which 32.7% and 20.4% were contributed by IPCA1 and IPCA2, respectively. This implies that the interaction of 17 chickpea genotypes with eight environments was predicted by the first two principal components. AMMI1 biplot analysis showed five adaptive categories of genotypes based on similarities in their performance across environments. The AMMI2 biplot generated using genotypes and environmental scores for the first two IPCAs revealed positioning of the five genotype groups (GC) into four sectors of the biplot. Among them, two genotypes in GC 5 (G5 and G11) exhibited high yields across environments, low IPCA1 scores, low AMMI stability value (ASV) and yield stability index (YSI). G5 was released as a new variety, ?Dimtu? and registered in the Official Varieties Catalogue of Ethiopia, 2016.
