Abstract :The study was conducted in 2014-2016 on the experimental field of the Institute of Forage Crops, Pleven, Bulgaria. The plant material from the aboveground and root mass of seven forage peas insert ignore into journalissuearticles values(Pisum L.); genotypes and varieties, i.e. X07P54, X06PWY, NDPO80138-B-2, CA1P, L020140, Wt6803 and Mir was analyzed. The ecological and genetic model for the organization of the quantitative trait and the method of the orthogonal regressions as a method of study and evaluation were applied. The highest and stable yield of fresh root mass was obtained at Wt6803 insert ignore into journalissuearticles values(12.9 kg ha-1);, NDPO80138-B-2 insert ignore into journalissuearticles values(10.9 kg ha-1); and L020140 insert ignore into journalissuearticles values(7.24 kg ha-1);. X07P54, X06PWY and CA1P were low productive insert ignore into journalissuearticles values(6.4 to 9.1 kg ha-1); and highly resistant to this signs. Stable green mass yields were Wt6803 insert ignore into journalissuearticles values(388 kg ha-1); and Mir insert ignore into journalissuearticles values(376 kg ha-1); ranked respectively with 1 and 2 rank. Plants from Wt6803 and Mir were shown good results on the modules productivity of fresh aboveground and root mass, and from NDPO80138-B-2 by nodule weight and fresh root mass weight per plant. The varieties Wt6803, Mir and L020140 are of interest to the selection due to the successful balance of physiological systems - attraction and adaptability to the weight of the fresh aboveground and root mass. They can be included in hybridization programs to obtain high-yield genotypes for these signs.
