Correlation between productivity and its main elements varieties of grain peas

The article presents the results of a three-year study of 137 genotypes of grain peas from the collection nursery for the period from 2014 to 2016. Research conducted in the fields of plant breeding crop rotation of FSBSI FRARC, located in the agro-climatic Azov zone of Rostov region. The variety samples were evaluated by the productivity of plants and its main elements: the number of beans and seeds from the plant, the number of seeds in the bean and the weight of 1000 seeds. As a result of the correlation analysis, it was found that between the productivity of the plant and all its main components, there are certain dependencies, the strongest of which is the dependence of this feature on the number of seeds from the plant.
