The article presents the results of the three-year research aimed at studying and determining lentil varieties with high yields, suitable for mechanized harvesting (tall with the high attachment of lower beans), maturing at the same time and non-shedding, as well as resistant to stress factors, for use in breeding. The objectives of the research include the study of lentil varieties in two agro-ecological zones (in the conditions of semi-supplied dryland and the conditions of irrigation in the Southeast of Kazakhstan) with the establishment of vegetation periods; phenotyping of economically valuable features and properties; determination of lentil grain quality. Lentil varieties of different ecological and geographical origin (31 varieties) are used as material. They are distinguished from each other by their main economic and valuable features and biological properties. Phenological observations and assessments were carried out in two agro-ecological zones. Phenotyping of productivity elements was carried out according to the method of studying the collection of leguminous crops. The biochemical analysis determined the protein content in lentil grain. The authors of this article have identified the following varieties with high crop yield and protein content that are of interest for selection. All selected varieties will be used in the breeding process to create high-yielding, high quality and drought-resistant varieties.
