The decline in the genetic polymorphism in maize is a cause of concern for many breeders. VIR maize collection represents the world’s maize variety over the past 100 years. The results of the study of maize quantitative properties based on 169 samples from the VIR collection created with the teosinte are shown. KB 595 hybrid, which belongs to the late-season group and is prone to multi-cob was used as a standard. Sowing and evaluation of phenotypic traits were carried out for 2 years in the foothills of Kabardino-Balkaria, in conditions of sufficient soil moisture, in the optimal time. All measurements were carried out on 10 plants with average values of 2 years and an LSD0.05. The results of the research allocated a core collection of 21 samples that promising for hybrid maize breeding and are characterized by significant height and leafiness of the stem, as well as a tendency to form 2 or more cobs on one stem. It has been suggested that the involvement of the selected core collection of 21 samples in thybrid maize breeding programs will significantly expand its genetic polymorphism and increase grain yield in hybrid combinations.
