Faba bean （Vicia faba L.） is grown world-wide as a protein source for food and feed. The importance of nutzients （micro and macro） for human growth is universally recognized. An investigation was camed out to select the most successful faba bean genotypes to estimate for seed yield and some of agro-morphological traits. Effective interpretation of the dataon breeding programes is important at all stages of plant improvment. The GT （genotype by trait） was used for two-way faba bean genotypes with multiple traits. For this purpose, six faba bean genotypes with specific components were tested and the GT biplot for genotype data explained 83% of total variation of the standardized data. The polygon view of GT presented for five traits of faba bean genotypes showed three vertex genotypes as Goryaka, Karcacaoglan and Seher. Genotype G0ryaka had the highest values for most of the traits. It was demonstzaited that the selection of high seed yield will be via hundred seed weight and planth height. These traits should be considered meanwhile as effective selection criteria developing high yielding faba bean genotypes because of their large contibution to grain yield. The genotypes Goryaka and Karacaoglan could be well-considered for improving of desirable candidate in selection of improvement studies.展开更多
