Abstract
The studies were carried out in 2020 at the "Berezanskoye" agricultural enterprise located in the Korenovsky district of the Krasnodar region. The aim of the research was to establish the possibility of improving the sowing qualities and yielding properties of the forming F1 seeds in the hybridization plot of a simple interline hybrid of sunflower Fakel. We studied the influence of various complexes of agrotechnical methods on plants of the maternal form of sunflower: application of the fertilizers, biological preparations and protection means against diseases and pests. The after-effect of the positive impact of the preparations was investigated in 2021 in a field experiment on studying the field germination of F1 seeds of the sunflower hybrid Fakel. It was found that during the formation of F1 seeds of the hybrid Fakel at the hybridization plot, the best results in terms of seed quality were obtained using a complex of fertilizers and chemical plant protection, where the highest values of the indicators of the yield structure were noted (diameter and formation of a head, seed amount per a head, 1000 seed weight, and volume weight). This made it possible in F1 to have lower losses of field germination for the formation of a scientifically based plant density. As a result of phytoexamination of grown seeds, it was revealed that the use of protective measures at the hybridization plot during the growing season of plants of the maternal form of the hybrid Fakel made it possible to increase the percentage of formed healthy seeds. The best data on the level of field germination of seeds were obtained when using biological plant protection and microbiological fertilizers at the hybridization plot. This ensured the smallest loss of germination at the scientifically grounded plant density of the hybrid Fakel in F1.
