Abstract

A computer graphic L-system-model simulating the final morphology of the barley (Hordeum vulgare L.) spike is presented. By applying different parameter sets to growth and branching rules, natural variation in spike morphology can be modelled visually. The biological relevance of the simulated phenotypes is enhanced in various ways: (1) constraints arising from parameter correlations are considered in the growth rules; (2) parameters are chosen to mimic the plant's morphology; (3) their ranges are based on those of real plants. The model is designed to predict and visualize phenotypes corresponding to diploid multigenic genotypes. Those are assembled from lists of alleles belonging to specified genes (or QTLs). Interactions of alleles (dominance, additivity) and of genes (epistasis) are computed from measurementsto predict values of morphological variables. Two examples illustrate the principles of the model: spikelet rows and awn length. The use of quantitative data supplied by analysis of QTLs is considered.
