Fed'ko N. Selection value of the self-pollinated lines of corn different germplasms for production of hybrids adapted to conditions of Steppe of Ukraine

Object - laws of display of selection and economic-valuable signs that define adaptation to Steppe conditions, at lines of different germinal plasmas and the hybrids created with their participation. Aim - an establishment selection and economic resources of the base self-pollinated lines of corn of different germplasms at creation of the highly productive hybrids adapted for cultivation in the conditions of Steppe of Ukraine. Methods - field tests, measure weight, statistical. Novelty - for the first time it is tested in the general scheme morfo-biological, economic, selection indicators base inbreds lines of corn of different germplasms and the hybrids created with their participation different heterotic models It is installed character of inheritance of selection and economic signs of lines and germplasms as a whole. Adaptive properties of samples are certain and are established optimum backgrounds for selection and an estimation of their ecological stability. Results: Lines which are included in selection process for reception adapted hybrids, tolerant crops to plant density with stable productivity are allocated. Sphere of use - Agricultural
