Abstract
The article discusses the results of the use of diallel analysis in the study of self-pollinated maize lines. The average values of the elements of the structure of the grain yield in self-pollinated lines, as well as the average group indicators of hybrids, are noted. The effects of the general and dispersion of the specific combinative ability of lines are revealed. The ranking of the average group values of hybrids by the weight of the cob was carried out, which made it possible to arrange the lines in the following sequence: CL 7 < X 46 < SE 19 < Od 28 < KS 25 < LV 32 < Bg 1266 < Om 255 < Uk12 D 2 < RSK 25 < Om 232 < Mk 130 U < RSK 3 s< RSK 7 < RN 26 < Mk 11. In 2016-2019 A significant influence on the manifestation of the weight of the cob, the weight of the grain from the cob, the yield of grain, the number of grains in a row and the grains on the cob of the paratypical component of the dispersion (E) was noted.
