Summary
In witloof-chicory fertilization is frequently prevented by the action of an incompatibility mechanism. In two experiments the incompatibility system was investigated. In the IVT phytotron at a constant temperature of 17 C reciprocal crosses were made between unrelated plants followed by diallel crosses between the F1 plants and backcrosses with the parents.
Analyses of the results of the above crosses strongly suggest that in witloof-chicory a one locus sporophytic incompatibility system occurs with different dominance and codominance relationships between S-alleles in pollen and style.
