APPLIED IMPORTANCE OF FUNDAMENTAL STDIES IN SELECTION AND SEED GROWING
The article presents the results of the genetic analysis and the revealed regularities of manifestation of the combined variability in the first, second and subsequent generations of hybrids, through which it is possible to forecast the number and the ratio of pulling out forms and to plan a selection of pair for interbreeding and a volume of hybridization. Theoretically grounded methods of working with hydride material enables one to obtain constant genotypes of different varieties already in the third generation when making individual estimation of descendants of the selected pulled out phenotype-identical but genotype-different homo- and heterozygous forms of structures under investigation. A relationship of selection and seed growing with genetics, cytology, anatomy, biotechnology, and gene engineering is shown.
