Summary The relationship was investigated between performance differences, and genetic distance between parental breeds, and heterosis increment in milk and fat yield. Heterosis increments were positively correlated with both yield difference and genetic distance but only the relation between heterosis of fat yield and genetic distance between parental breeds was statistically significant. It appears that measures of genetic distance could provide a useful tool in selecting breeds for crossbreeding.
