چکیده مقاله:
Sainfoin (Onobrychis viciifolia Scop.) is a perennial forage legume, widely distributed in the northern temperate region and has received renewed interest in the world. This experiment was carried out to proceed from the previously-produced Syn۱ generation of a new synthetic variety to the Syn۲ generation. The Syn۲ generation was produced and evaluated during the ۲۰۱۵-۲۰۱۹ growing seasons. In the first two years, the seeds of the Syn۲ generation and composite varieties were produced in completely isolated condition. Then, the Syn۲ generation along with the Composite, Sarab, and Bostan-Abad varieties were evaluated in the field conditions for three years (۲۰۱۷-۲۰۱۹). Significant differences were observed for the fresh and dry matter yield and plant height among the studied sainfoin varieties. The Synthetic variety showed the highest annual fresh forage yield (۳۶۷۸۵ kg ha-۱) which was significantly different from other varieties. A similar result was obtained for the annual total dry matter yield, and the Synthetic variety showed the highest dry matter yield (۱۱۷۱۵ kg ha-۱). The superiority of the Synthetic variety over the average of the ecotypes of Sarab and Bostan-Abad was about ۲۵% for the dry matter and fresh forage yield. The plant height of the Synthetic variety was ۸۳ cm, which was higher than other varieties. Among the studied varieties, no significant differences were observed for the traits related to forage quality. The protein content, total ash, crude fiber, water-soluble carbohydrates, and acid detergent fiber in the Synthetic variety were ۱۸.۵۲, ۷.۴۰, ۱۹.۹۵, ۴۴.۷۰, and ۱۹.۶%, respectively. The results indicated
