Abstract
Lentils (Lens culinaris Medic.) belongs to the group of valuable high-protein food crops. A significant role in increasing its productivity is given to breeding. Among the methods of statistical data processing, the analysis of correlation interconnection between characteristics has become widespread in selection. Therefore, the aim of the research was to determine the correlation between the main economically valuable traits of lentil collection samples in the conditions of the Omsk region. Research project was carried out in 2016–2018 on the sidelines of the training and experimental farm of the Omsk State Agrarian University, located in the Southern forest-steppe of Western Siberia. The object of the study was the collection samples of lentils of different ecological and geographical origin (Russia, Germany, Turkey, Canada, Bulgaria, Moldova, Ukraine, Belarus, Kazakhstan). The standard was the Aida variety. Over the years of research, according to the results of the correlation analysis, a stable interconnection between the yield and the number of beans (r = 0.80 ± 0.04) and the mass of seeds (r = 0.80 ± 0.04) per plant was fixed. An average positive interconnection between yield was found during the periods from germination to flowering (r = 0.60 ± 0.09) and from flowering to ripening (r = 0.60 ± 0.09), the number of seeds in a bean (r = 0.60 ± 0.09), weighing 1000 seeds (r = 0.50 ± 0.09), the distance from the tip of the lower bean to the soil (r = 0.40 ± 0.08) and the height of the plant (r = 0.40 ± 0 , 08). A weak positive dependence of the yield was fixed on the length of the bean (r = 0.30 ± 0.07) and the height of attachment of the lower bean (r = 0.30 ± 0.07). The analysis showed the degree of influence of various elements of productivity on the formation of productivity, which affords more targeted selection in the selection process.

Summary
Поэтому целью исследований являлось определение корреляционной связи между основными хозяйственно-ценными признаками у коллекционных образцов чечевицы в условиях Омской области. За годы исследований по результатам проведенного корреляционного анализа зафиксирована устойчивая взаимосвязь урожайности с количеством бобов (r = 0,80±0,04) и массой семян (r = 0,80±0,04) с одного растения. Средняя положительная связь урожайности обнаружена с длительностью периодов от всходов до цветения (r = 0,60±0,09) и от цветения до созревания (r = 0,60±0,09), количеством семян в бобе (r = 0,60±0,09), массой 1000 семян (r = 0,50±0,09), расстоянием от кончика нижнего боба до почвы (r = 0,40±0,08) и высотой растения (r = 0,40±0,08). Слабая положительная зависимость урожайности зафиксирована от длины боба (r = 0,30±0,07) и высоты прикрепления нижнего боба (r = 0,30±0,07). Проведенный анализ показал степень влияния различных элементов продуктивности на формирование урожайности, что позволяет более целенаправленно проводить отбор в селекционном процессе.
