In contrast to the yellow color of pollen of European hazelnut (Corylus avellana L.) cultivars, an unusual cream color was observed in some seedlings from self-pollination of the Sicilian cultivar ‘Montebello.’ After elimination of accidental outcrosses, the segregation fit a 3 yellow: 1 cream ratio, indicating the possibility of simple genetic control. Two seedlings with cream-colored pollen were backcrossed to their parent ‘Montebello,’ and the progeny segregated 1 yellow: 1 cream for pollen color. When two seedlings with cream-colored pollen were crossed with each other, all of the resulting seedlings had cream-colored pollen. These segregation ratios indicate that pollen color in hazelnut is controlled by a single locus with yellow dominant to cream color. The symbol pc is proposed for this locus.
