Özet: Forage pea (Pisum sativum spp. arvense L.) is one of the annual cool-season legume forage species. It has high forage yield and forage quality, when harvested in the appropriate period of the plant. Due to the superior features of the species, many researchers have intensively studied on the species in Turkey for improving new cultivars in the recent years. As a result of the intensive breeding studies carried out the Southeastern Anatolia Region ecological conditions, the first forage pea variety of the region, GAP Pembesi, was registered. When compared the other annual legume forages, the outstanding feature of the GAP Pembesi cultivar is its earliness in flowering and seed maturing time. Moreover, it was found remarkable in terms of both forage yield and seed yield. According to the results of field trials conducted at different times and locations, determined means of some characteristics of the GAP Pembesi forage pea cultivar were as follows; natural plant height-85-110, main stem length-100-180 cm, main stem thickness 3.5-5.5 mm, fresh forage yield 2500-3500 kg da-1, dry forage yield 600-800 kg/ha, crude protein ratio in the dry matter forage 20-22%, the number of pods per plant 10-30 pods/plant, seed number per pod 5-7 seeds/pod, biological yield 700-800 kg da-1, straw yield 500-550 kg da-1, seed yield 250-300 kg da-1, harvest index 35-40% and thousand grain weight 160-210 g. As a result, cultivation of forage pea by choosing the GAP Pembesi cultivar in the Southeastern Anatolia Region ecological conditions not only will contribute to the sustainable use of our agricultural lands but also making significant contributions to supply quality roughage that its shortage is one of the biggest problem of animal husbandry of Turkey.
