*2.4. Data Collection*

Although all of the genotypes successfully passed the seedling period and bloomed, limited seed holding was occurred in 184 genotypes. The qualitative traits were recorded for the initial collection (274 accessions). However, 94 lines were used to get observations for quantitative and nutritional traits. Grass pea descriptors [4] were used for recording qualitative and quantitative characteristics. Plants were characterized by the following traits: days of first flowering, days of 50% flowering, plant height, pod number per plant, number of branches per plant, pod height, pod width, stem diameter, hundred seed weight, biological yield per plant and seed yield per plant. In addition, β-ODAP, raw protein, acid detergent fiber (ADF), and neutral detergent fiber (NDF) were determined from the seeds of grass pea.
