The results of research on establishing the correlation-regression dependence of the assimilation surface area of plant leaves of inbred lines-parental components of corn hybrids of different FAO groups and seed yield depending on the density of plants and treatment with the drug Retengo® are highlighted. The research is based on a comparative assessment of three parent lines of different FAO groups: DK247 (FAO 290), DK205710 (FAO 380), DK445 (FAO 420). The effectiveness of the application of the fungicide with growth-stimulating action Retengo® at different plant densities was determined. The yield calculation showed that the realization of the seed yield potential for each inbred line depends on the genotype, in accordance with the established individual parameters of the optimum leaf surface and phytocenosis density in the crop. The use of the fungicide with growth-stimulating action Retengo® strengthens the correlation of the area of leaves of plants of lines and the yield of seeds.
