Methods of phenotypic labeling of white clover varieties

For breeding achievements, the method of identifying varieties is of great importance, on the basis of which an opinion is given on their novelty, distinctiveness and legal protection. The study presents the application of phenotypic markers on the white clover culture. The search for genotypes having distinctive phenotypic features is carried out at all stages of the breeding process. There is a working collection of phenotypic markers on the pattern of the leaf plate, anthocyanic color of the leaves and multi-leaf. Iso-genic populations with a specific marker trait are created from selected individual plants or groups of plants through manual pollination and repeated selection. Isogenic populations with marker traits have been created: "filled white leaf plate mark", "elongated leaf plate mark", "absence of a white mark on the leaf plate", and "pink inflorescence color". Phenotypically marked samples can become varieties them-selves or be used for marking promising breeding material. The experiment demonstrates the possibility of phenotypically marking promising breeding material of white clover using the marker trait "pink inflo-rescence color". It has been shown that the inflorescence color trait is transmitted in the F1 and F2 genera-tions.
