Grass pea (Lathyrus sativus) is a naturally growing crop in Turkey and it is considered a valuable fodder resource to improve soil properties and livestock farming. This study was carried out in the laboratories of Bingol University between 2019-2020. In the study, some physical (shape-size, surface area, projection area, average arithmetic diameter, thousand grain weight) and physiological (germination rate and time) characteristics of the seeds belonging to twenty-four different genotypes of grass pea were determined, and the results were evaluated according to the randomized blocks experimental design with four repetitions. According to the data obtained, all grass pea genotypes have a short and oval seed structure, with an average length of 6.010 mm, average width of 5.369 mm, a surface area of 28.773 mm2, a projection area of 25.830 mm2, an arithmetic diameter of 5.690 mm and a thousand grain weight of 126.688 g. It was determined that all grass pea genotypes germinated at a rate of 85-100% within 0.508-0.538 days.
