Relevance. Vegetable beans (Phaseolus vulgaris L.) – a valuable high-protein culture, which has multilateral use in the national economy, is recommended for dietary nutrition. The protein content in green beans and seeds varies from 18 to 30%, which in terms of amino acid composition is at the level of protein in milk and meat.The aim of the research is to create a new indeterminate medium-late resistant to major diseases varieties for farms growing that provide fresh produce (green beans) with a long fruiting period, without fiber and parchment in the leaflets of the green bean.Methods. Studies were carried out from 2008 to 2018 on breeding fields of the Federal Scientific Vegetable Center (Moscow Region, Odintsovo District). Scientific work was started in 2013 with an individual selection from collection sample No. 90K (Republic of Crimea). Since 2015, the constant form was propagated with a two-year test of offspring. All the necessary phenological, biometric and phytopathological observations and counts were performed according to the methods generally accepted for this culture.Results. The article presents data on a new variety of vegetable beans Malume of indeterminate (curly) type of growth. As a result of competitive variety testing in the conditions of the Central Non-chernozem Zone since 2018 to 2019, against a natural infectious background, the new variety significantly exceeded the Fatima standard for the yield of green beans and seeds, was characterized by a high content of mono-, the amount of sugars, starch, and was resistant to major diseases. At the end of 2019 year transferred to the State Variety Test.

The main problem of agroindustrial sector of national economy is an absence of sufficient production of plant proteins that are used for food production as well as a forage production. New cultivars of legumes, namely in soybean have to be developed to resolve this task. Soybean seeds contain much protein up to 50%, fat up to 28 %, along with vitamins, phospholipids, isoflavones and ferments. Soybean is a short-day crop. The main reason that limits the spread of soybean is the absence of new early-ripening cultivars. Folk cultivars and varieties native to China produce the grain yield at the sum of temperatures over 3500oC. At the beginning of the last century, there were bred the varieties that produced the grains at the sum of temperatures below 3000oC. Only after that the soybean as a crop is started to be introduced in different countries. The study on association among quantitative traits is needed to select necessary accessions for breeding program. In this research estimation of correlationship based on data of structure analysis was carried out within two-year period. The correlationship of economically valuable traits, such as 1000 seed grain weight, number of grains in bean (pod) and other traits such as plant height, stem thickness, the height of pod attachment, a number of branches, number of pods on the plant, number of productive nodes, average number of pods at node, average number of grains (beans) per plant in field experiment in 2015-2016, Central Zone of Non-chernozem Zone of Russia. It was noticed the difference in trait correlationship depended on a year, and it needs to be taken into account for realization of breeding program in soybean.
