    Uittreksel

    As in other crops, evaluation of grass genotypes requires objective measures
    of the performance of individual plants or swards. However, because
    of genotype-by-environment-by-management interactions, the genetic
    value of a genotype cannot always be easily assessed. Detailed ecophysiological
    models that describe physiological processes determining phenotypic traits consist of parameters that can be considered as genetic coeffi cients that better represent the genetic value of the genotype. We used the LINGRA grass model to estimate model parameters for a perennial ryegrass variety based on harvest data from seven growing seasons. Despite its relative simplicity, the LINGRA model succeeded in simulating the dry matter harvest of different years, although it substantially underestimated the yield in the driest year. The grass-specifi c LINGRA features should therefore be combined with a more extensive ecophysiological model to enable reliable estimation of genotype specific
    parameters.
