Stability Analysis of Finger Millet Genotypes in Moisture Stressed Areas of Northern Ethiopia

Nine advanced finger millet genotypes along with local check and standard check (Tadesse) were evaluated at moisture stressed finger millet growing areas of northern Ethiopia. Experiments were conducted in Rama during 2012, 2013 and 2014, in Ahferom during 2013 and 2014 and in Maistebri during 2014 cropping season, to select and recommend best yielding stable genotypes. AMMI, ASV and GGE methods of genotype by environment interaction analysis, showed that KNE#622 gave high grain yield performances and was relatively stable. Therefore, this genotype can be recommended for moisture stressed areas. Results indicated that the local check and standard check were the worst varieties for their high environmental interaction and low grain yield.
