AB  - A dataset of 27 787 first-lactation cows with a minimum of 51% of Czech Pied cattle in genotype (CA) was analysed with the aim to evaluate relationships among type traits and characteristics. The dataset included a sub-population of 5 796 pure-bred Czech Pied cows (CP). Linear type traits and general type characteristics were evaluated. The following 17 linear type traits were scored (on the scale of 1-9): stature (LP 1), rump muscularity (LP 2), rump length (LP 3), rump width (LP 4), rump angle (LP 5), body depth (LP 6), rear legs set (LP 7), hock (LP 8), foot angle (LP 9), hoof (LP 10), udder length - fore quarters (LP 11), rear udder height (LP 12), central ligament (LP 13), udder depth (LP 14), teat placement (LP 15), teat length (LP 16) and teat thickness (LP 17). The four general type characteristics (the score 50-100) were as follows: frame (E 1), muscularity (E 2), legs/feet (E 3) and mammary (E 4).The highest coefficients of correlation among linear type traits (r>0.5) in CA and CP, respectively, were found between LP 3 and LP 4 (0.720 and 0.725, respectively), LP 1 and LP 3 (0.510 and 0.516, respectively), LP 1 and LP 6 (0.526 and 0.535, respectively) and LP 4 and LP 6 (0.503 and 0.492, respectively). The highest coefficients of correlation (r>0.5) between linear type traits and general type characteristics were found in CA and CP, respectively, between E 2 and LP 1 (0.958 and 0.956, respectively), E 1 and LP 1 (0.835 and 0.833, respectively), E 1 and LP 6 (0.753 and. 0.756, respectively), E 1 and LP 3 (0.750 and 0.758, respectively), E 1 and LP 4 (0.744 and 0.755, respectively), E 4 and LP 11 (0.720 and 0.713, respectively) and E 4 and LP 12 (0.716 and 0.744, respectively). No coefficient of correlation between general type characteristics was greater than 0.5. No significant differences were found (maximum difference 0.147) between the coefficients of correlation in the whole population (CA) and in the pure-bred sub-population (CP).
