DETERMINATION OF THE GENETICALLY VALUABLE CORN SAMPLES AT THE CREATION OF THE SOURCE MATERIAL FOR THE CORN SELECTION

For selection of the lines of new generation were used the donors of tolerance to the disease exciters and introduced the modified methods of artificial infection and selection that allowed create the new source material of corn. There were received 302 lines of UKC (Ukraine, Kharkiv, Chernobay) tolerant to the bubble smut that are characterized with valuable agricultural signs. Among them were separated 21 lines with the high productivity and valuable agricultural signs: UKC 85-2, UKC 80-3, UKC 80-2, UKC 135-2, UKC 155-2, UKC 96, UKC 86, UKC 142, UKC 83, UKC 96-2, UKC 129-2, UKC 164,UKC 83-2, UKC 88-2, UKC 131, UKC 147, UKC 144-2, UKC 167,UKC 164-2, UKC 90-2, UKC 163-2; were created lines with the complex tolerance to the bubble smut and crop moth with the high productivity: UKC 144-2, UKC 167, UKC 164-2, UKC 90-2, UKC 163-2. The UKC lined were included into selection work in the laboratory of selection and seeding of the corn of the Institute of crop production of V. Y. Yuriev, NAAS of Ukraine
