title: [The question of correlation coefficients between successive measurements in plant breeding research].
abstract: The analysis of variance normally is conducted under the assumption of no correlations between residuals. Sometimes this assumption is violated in plant breeding experiments. If it is ignored, the estimates of mean squares and variance components are biased. For some restricted models the correlation is estimated from experiments with Gerbera, tulips and potatoes. Often a positive correlation was found, but never a negative one. The consequences of such correlations are discussed.
