摘要：

Data on 331 321 racing performances of all competing trotters in the Federal Republic of Germany have been filed since 1973. After adjusting to environmental factors, repeatabilities and heritabilities of the most important traits (racing time, money earnings and perfect gait) have been estimated. The highest degrees for repeatability (rbetween years = 0.55-0.79) and heritability (h2 = 0.21-0.49) are found in the average racing time per year. Therefore, this trait should be the main selection criterion in a practical breeding programme. © 1979.
