The structure of the seed yield of broad beans in the south central zone of the south of the Central Black Earth region

Rich in high quality protein, vitamins, carbohydrates, organic acids and trace elements seeds, green fruits and young leaves broad beans (Vicia faba L. var. major Harz) has long been used in the food, and the culture of beans are promising in biological agriculture and horticulture. The aim of this work was to study the structure of seed production of different varieties of broad beans in the South Central zone of the region. At the Botanical garden BelSU (Belgorod) to study the structure of seed production of different varieties of broad beans (Belarusiskie, Velena, Russkie chernie, Aquadul) and determined the biochemical composition of seeds. Optimal height of attachment of the first fruit for mechanical harvesting (20-25 cm) characteristic of plants of all studied varieties. Weight of the fetus, according to the coefficient of variability, equal to 45%, distinguished by a strong variability on grades with a maximum grade of Velena. The length of fruit ranged from 9 to 13 cm and were characterized by moderate variability (V=20%). Seeds production is determinened not only by size of fruits of beans, but and its important components such as 1000 seed weight. Protein content in the seeds at 30% different varieties of broad beans domestic breeding. Contents of nitrogen, potassium, phosphorus and iron is higher in the cotyledons than in the skin. Dark purple color of the seed varieties of Russian black is due to the biosynthesis useful for human organism anthocyanins in seed peel.
