| Popis: | The article presents the results of the study of new hybrid combinations of rediploid maize lines obtained by the diallelic scheme of crossing. The experiment involved simple hybrids of six homozygous lines. The degree of manifestation of heterosis according to the main morphometric parameters of the plant (stem length, ear height, panicle length, stem diameter), as well as the combinative ability of lines and components of genetic dispersion, was revealed. The ways of possible use of lines and hybrids in the breeding process are noted - for tall stature, resistance to lodging, manufacturability. The influence of overdominance in the manifestation of the length of the panicle and the diameter of the stem and the predominance of additive effects in the formation of the height of the ear were noted. Analysis of the components made it possible to identify the number of genes or groups of genes that influenced the manifestation of traits in 2021 (stem length - 1-2, cob height - 2-3, panicle length - 1-2, stem diameter - 2-3). A significant influence of cultivation conditions on the manifestation of the length of the stem, the height of the cob, the length of the panicle, and the diameter of the stem was noted.1. |
