The research focused on breeding and genetic improvement of the initial material of maize and sugar siliceous subspecies by conventional breeding and experimental mutagenesis and synthesis on their basis of highly productive, adaptive hybrids, able to consistently realize their productive potential in various growing conditions. Studied 83 new line, the final selection of the 22 best lines. Received 11 sterile analogues of M - type and 13 vanousova fertility of M - type, 9 sterile analogues of C-type and 4 vanousova fertility of C-type. The study of the reaction 14 6 duplicated lines and sterile analogues and reducing agents. Held the rejection and subsequent ncuhc new lines I1 - I8, formed on the hybrids of different origin and of different groups of maturity by ncwhtu. Selected 88 lines I1 and I2 447 lines. On a broad the source material studied patterns of inbreeding depression and the formation of economic-biological features and properties samozaryadnyj lines. In the studies selected siliceous 53 inbred lines, which are indicators of: productivity, resistance to adverse growing conditions, breakage of the stem greatly exceeds the standard samples. In result of conducted research selection of the best 23 lines of sweet corn on the individual productivity characteristics far exceed standard samples For the study period 2011 - 2015 years in the nursery of the control trials was studied 2875 corn hybrids, and in the nursery of competitive variety trials were studied 1330 maize hybrids. Based on five years of research created and prepared for the state variety testing 1 siliceous hybrid Experimental 19/15 FAO 200, 1 middle-early hybrid of sweet corn Experimental 1324/15, 2 criminalizable hybrids Experimental 65/15 FAO 250 and Experimental 82/15 FAO 300. In 2013, listed in the national register of mid-season hybrid of corn, the Abundance of 300 MV in the direction of use for grain and silage.
