ECOLOGIC ADAPTABILITY AND STABILITY OF VARIETAL SAMPLES OF SPRING VETCH (VICIA SATIVA)

At present it’s necessary to supply the population with the animal food of domestic producers. The fulfillment of the task becomes possible if the agricultural animals are provided with the full balanced feeding. The increase of cultivation of the leguminous grasses is one of the main ways to increase of production of vegetable protein. Spring vetch is one of the most promising leguminous crops in the Primorie. Among the leguminous annual grasses spring vetch possesses the largest content of digestible protein, carbohydrates, oils, various vitamins and minerals. In the Primorsky Kray the collection of spring vetch varieties has been studied in the mixed cultivation. The most productive and sustained variety samples, suitable for the further breeding have been determined. The varieties ‘Nikolskaya’ and ‘Yubileynaya 110’ showed the highest productivity of seeds per 1m2 (135.09g and 139.08g respectively). The variety ‘Omichka 3’ (76.74g) had the highest productivity among the control varieties. During the study of spring vetch we estimated the varieties with the best productivity of green chop per 1m2, they are ‘Lugovchanka’Russia (1.17kg); ‘Nemchinovskaya 72’Russia (1.34kg); ‘k-35451’Hungary (1.36kg); ‘k-35415’Syria (1.40kg); ‘Hifa’France (1.20kg); ‘Lugovskaya 85’Russia (1.41kg). The samples ‘Nemchinovskaya Yubileynaya’ (Russia), ‘Ugolek (Russia), ‘Lugovchanka’ (Russia), ‘Nemchinovskaya 72’ (Russia), ‘k-35451’ (Hungary), ‘k-35415’ (Syria) are characterized with high adaptability in the productivity of green chop. The varieties ‘Yubileynaya 110’ (Russia), ‘Hifa’ (France), ‘Lugovskaya 85’ (Russia), ‘Nemchinovskaya 72’ (Russia), ‘Elena’ (Russia) are considered to be the sustained ones. The assessment of the control varieties on productivity of green chop showed that the variety ‘Lugovskaya 85’ was more sustained (Sdi 2=0.10) than the variety ‘Omichka 3’. The variety samples are of great interest for use as an initial material of spring vetch in the Premorsky Kray.
