Adaptability study and yield stability analysis of lentil (Lens culinaris Medik) varieties at East Hararghe Oromia Ethiopia

Evaluation and selection of lentil varieties with wide adaptability across diverse environments is very important, before recommending them to achieve a high rate of varietal adoption. Because lentil yield is a complex quantitative attribute that is highly impacted by the environment, many tools were used to investigate multi-environmental trials and recommend optimal varieties and conditions. The Genotype by Environment Interaction (GEI) and AMMI (Additive Main Effects and Multiplicative Interaction) tools were used to estimate seed yield by analyzing variation in variety yields across mult-environments. The ideal-genotype biplot revealed that Alemaya-98 and Assano outperformed all other varieties, with both exhibiting high mean yield and good performance stability across environments. According to genotype-environment interaction sources of variation, Girawa 2022 was the most appropriate environment for lentil cultivation. As a result, the Alemeya-98 and Assano variety were suggested for further demonstration and production.
