Georgieva, N., & Kosev, V. (2020). Model of forage pea (Pisum sativum L.) cultivar in conditions of organic production. Bulg. J. Agric. Sci., 26(1), 91–95
The requirements which the production systems with reduced levels of inputs and, in particular, organic production, impose on the cultivars, present a new challenge in the pea breeding. In the present study a linear regression equation was obtained defining the main traits which should be taken into account when choosing the source material for hybridization and their optimal matching would result in a forage pea cultivar with increased productivity. The results showed that the model for pea plant suitable for organic production conditions was characterized by the following parameters: stem with a height of 75-85 cm, forming 6-7 pods with a total number of seeds 20-25, length and width of the pod respectively 5 cm and 1 cm, and a mass of 1000 seeds in the range of 200-230 g. The cultivars Svit and Kamerton could be recommended as suitable parental components, combining high ecological stability with productivity.
