Methods: hybridigation, individual and mass selection. It is relatively resistant to diseases the table hybrid beetroot Rytsar F1 was created with the help of intervarient hybridization. Vegetative season is 80- 90 days. The root of flattened form. A root mass is 200 - 250 g. The root crop capacity is 56- 59 t/ha, marketability - 95- 97%. Good condition 90- 91%. Chemical composition: dry matter 15- 17%, general sugar 8- 9%, ascorbic acid 10- 12 mg/100g, betanin 480- 570mg/100g. Hybrid Rytsar F1 is adjusted to the temperature raising and lack of humidity. The variety spinach Peremozhets. It is early- repen, verdure crop capacity is 21,2 t/ha, dry matter 12,9%, vitamin C- 84,0 mg/100g. The patent for useful model (№46365 from 20.10.2009) rad been taken out, which was used in acceleration of selection process. Lines: 1) table beetroot №1719, cylinder root, wine-coloured leaves. The content of betanin is 305- 340 mg/100g, crop capacity 30-34 t/ha; 2) spinach №87, the line has prolongated period of ripeness - 24 days. Crop capacity of verdure is 18,6 t/ha. It is given to state conseem standard: the project for SSTU "Spinach fress. Technical conditions"; SSTU "Maternals of table beetroot. Technical conditions".
