Kulinich O. Creation of selection material of lentil adapted to the conditions of the Ukrainian northern part of the Steppe

Object - creation and selection of breeding material with increased adaptive ability. The purpose - basing and application the principles of creation high yielding lentil breeding material adapted to the conditions of the Ukrainian northern part of the Steppe. Methods: field and laboratory-field experiences. Results: On the basis of comprehensive researches and system analysis were established peculiarities of lentil subspecies Macrosperma and Microsperma on their yield potential, pests and diseases resistance, identified them on common and specific adaptive ability. It was showed the affectivity of using hybridization between lentil subspecies for creation of high yielding breading material. Complex studying regularities of exhibition and variability of economic-valuable attributes is carried out; their interrelations and interdependence are established. Character of inheritance in inter-subspecies crossing was determined. As a result of four-year investigations conducted in 2003-2006 a number of heavy-producing lentil varietal samples promising for the development of varieties adapted to the conditions of the Ukrainian northern part of the Steppe and having valuable qualitative indices are singled out. The basic requirements to the lentil variety adapted to the conditions of this zone are substantiated. New lentil variety Linsa was passed to the State variety estimation and registered for planting in the Steppe of Ukraine. Sphere of use - Agricultural.
