The goal of this thesis was to assess colour inheritance in Showa tricolour variety of koi carp (black basis, white and red signs). Fish of the same colouration were pair-mated. Colouration of fingerlings was assessed in one day age. Colouration was observed in two forms, like melanin pigmentation and non-melanin pigmentation (black- pigmented and gold -pigmented fingerlings). In the tests, gynogenesis was employed, transmissing only mother`s genome to offspring. Gynogenesis was practiced in RIFCH USB in Vodnany. Gynogenetic offspring was further photographically documented to assess colouration of fingerlings and relationship between both variants of colouration. Fry from propagation was bred in ponds to the size stage of advanced fry (Kr; 90-day old, size 5- 6 cm). In this size, fingerlings were caught from breeding ponds, counted and further documented to check phenotype segregation.
