This analysis involves altogether 3569 horses (5,148 results) - GH, 4,168 horses (6,530 results) - IDP. Horses under study represented progeny of 519 sires (GH), 583 sires (IDP). Performance was analysed with regard to the following effects: sex, age, year of start, number of starts, breeder and trainer. Effects of all these factors was highly significant (P0.001) - the criterion general handicap (GH), effects of sex, age, number of starts, breeder and trainer was highly significant (P 0.001)- the criterion an index of performance (IDP).
