Abstract: This study was carried out in Mediterranean climate and under rainfed conditions in Turkey for a period of three years throughout the growing seasons of 2014/2015, 2015/2016 and 2016/2017. It was conducted in a randomized complete block experimental design (RCBD) with three replications. In present study, genetic diversity for agro-morphological characters and macro/ microelements were investigated in sixteen promising local faba bean genotypes originated from Turkey. According to the results of the study, mean grain yield varied from 2320 kg ha^-1 (Tekirdağ-39) to 3130 kg ha^-1 (Burdur-50). 100-grain weight and branches per plant had high heritability and genetic advance as a percentage of mean. As for path analysis; plant height, branches per plant and 100-grain weight had a major role in improving the grain yield of faba bean. Therefore, effective selection for mentioned traits can be made for increasing grain yield in faba bean. Wide diversity for macro and micronutrients in the studied local genotypes can be considered for improving new faba bean cultivars in Mediterranean climate conditions as well.
