ABSTRACT

The multi-location trial and stability analysis are important to identify wider adapted and specific adapted genotypes which is cultivated in different agro ecology of the country. AMMI and GGE biplot stability model used to identify stable and specific adapted genotypes of fenugreek across different locations. Eleven pipe line genotypes and two standard checks (Chala and Burka) grown in seven different locations to identify wider and specific adapted genotypes. Genotypes FG-12 and FG-4 identified as stable or wider adapted genotypes which are suitable to cultivated across the test locations where as genotypes FG-10 and FG-1 identified as specific adapted and suitable for unfavorable and favorable environments, respectively. Thus the four genotypes could be evaluated further to develop as varieties for the environment(s) the genotypes best suited. In addition, FG-12 had yield advantages of 10.39 and 35.69% over the grand mean and standard check (Burka/FG-13), respectively, while FG-4 had 4.53 and 28.49% yield advantages over the grand mean and standard check, respectively.
