Abstract

In the southern forest-steppe of Western Siberia the shortage of proteins can be overcome cultivating legumes such as beans, peas, broad beans and chickpeas. The varieties of dry and green beans bred at Omsk State Agrarian University are adapted to the conditions of the southern forest-steppe; they are characterized by high and stable productivity and possess high compensatory abilities as regards unfavourable environmental factors (drought, waterlogging, ground frost and others). The aim of the research was to determine the technological and nutritional parameters of the grains of common bean varieties bred at the University (protein and sucrose content, seed cooking rate). 6 varieties of common beans bred at the University served as research materials. As a results, the following varieties were identified as possessing valuable technological and nutritional properties: high protein content – Fizkulturnitsa (23.75 %), Lukerya (23.6 %), Omskaya yubileinaya (24.6 %) and Olivkovaya (25.5 %); high zinc content – Fizkulturnitsa (36.86 mg/kg), Lukerya (40.93 mg/kg) and Olivkovaya (40.35 mg/kg); high iron content – Olivkovaya (108.00 mg/kg); high iodine content – Lukerya (0.23 mg/kg) and Olivkovaya (0.21 mg/kg); high calcium content – Fizkulturnitsa (1.86 %); fast seed cooking rate – Fizkulturnitsa, Omichka and Lukerya (57-59 min); high sucrose content in the leaves – Omichka, Olivkovaya, Lukerya and Fizkulturnitsa (0.10-0.15 %).
