FIELD: agriculture.
SUBSTANCE: invention relates to the biochemistry of plants. Homozygous individuals are obtained through anther culture, followed by recovery of the gene complexes source hybrid by hybridisation of genotypically contrast range of dihaploid lines. And the hybridisation includes only the most productive dihaploid lines and the contrast range of dihaploid lines is evaluated on a complex of characteristics of morphological, physiological, biochemical, and molecular markers (SSR, SNP, etc.), the contribution of genetic systems in the productivity of the sample, and the totality of all the proposed methods. The method proposed by the authors enables more effectively than using the previously proposed methods to clean the original hybrid genotype, to accelerate the process of accumulation of genes that determine the heterosis effect, to abandon long and very difficult maintenance of the plant viability (during its several ordinary life cycles) of the original hybrid and to avoid problems connected with obtaining rising generation from it.
EFFECT: invention reduces the process of accumulation of the original complex of genes determining the heterosis effect, and of nearly double removal of genes which reduce productivity and viability of the hybrid.
