The study of selection lenil specimens vegetation period

One of the most important problems in the selection of lentils (Lens culinaris Medic.) is the reduction of vegetation period while maintaining a sufficiently high productivity. Geographical position of the Omsk Region is associated with very harsh climatic conditions; therefore, already at the initial stages of selection work, it is necessary to select the samples with high potential for ontogenetic adaptation. The research work was carried out in the fields of the teaching and experimental farm of Omsk State Agrarian University located in the southern forest-steppe of Western Siberia in 2016- 2018. As the object of the study the samples of lentils different ecological and geographical origin (from Russia, Germany, Turkey, Canada, Bulgaria, Moldova, Ukraine, Belarus and Kazakhstan) were chosen. The standard was the Aida variety. No clear relationship between early flowering and early maturation in the course of research (r = 0.32 has been established). The calculation of the coefficient of variation showed that flowering-ripening period of all samples was subject to greater variability (V =%) than shoots - flowering (V = 11...
