| Popis: | The expansion of the areas under sowing of sweet sorghum in the Lower Volga region is constrained by lack of varieties and hybrids well adapted to the conditions of the bathrooms in the region. With the purpose of studying initial material for creation of highly productive, competitive varieties for three years, conducted a comprehensive assessment of the 85 breeding lines of sugar-tion of sorghum. As a standard we used regionalized variety Volzhskoe 51. The result of the research found that, selectitional lines of sweet sorghum L-16, L-25 and L-42 you can select precocious. L-84 and L-115 had plant height by an average of 12.5% higher than the cultivar Volzhskoe 51. The fat content in herbage breeding line did not differ significantly from varieties of the standard, except for the line L-8 and L-115, which gave the variety Volzhskoe 51. Line L-3, L-5, L-8, L-84 significantly exceeded the grade standard of the Volzhskoe 51 according to the percentage sugar content in the juice in the phase of its emergence. Yield of green mass of sugar sorghum lines L-3, L-13, L-26, L-60, L-84, L-109, L-115, L-1106 exceeded the grade standard 16,5-by 36,4%. Yield of dry matter only lines L-23 and L-109 significantly exceeded the cultivar Volzhskoe 51 average of 26.6%. Selection-tion line L-1898/2 had the value of the trait «weight of 1000 grains» by 13,4% higher than sort-standard. All studied lines for grain yield exceeded the grade-a standard average of 50,7%, with the exception of line L-25, which did not differ from the standard. Thus, the results of scientific research have identified prospective lines, which significantly exceeded the grade standard of the Volga 51 in the complex of economically valuable features and properties. Breeding lines of sweet sorghum: L-109, L-1106 L-1327, L-1898/2 and L-84 is recommended for further testing. The best breeding line to consider crossing for obtaining hybrids of grain and forage sorghum. |
