RELATIONSHIP BETWEEN PRODUCTION OF ALBINO BERRIES AND MIXOPLOIDY IN THE STRAWBERRY (Fragaria x ananassa) CV. KENT

S. Plante, H. Rousseau
Albino strawberries have been found on a large scale in the Province of Quebec during summer 1997 and 1998. As clonal origin seemed to be correlated with this disorder, we characterized normal and abnormal plants by RAPD and chromosome numbers. RAPD analysis did not yield polymorphism. However, chromosome counts revealed mixoploidy in 63 % of the cells evaluated in the abnormal plants compared to 40 % in the normal plants; numbers of chromosomes varying from 44 to 106 and 51 to 105 respectively. The results suggest that there could be a critical level for the presence of mixoploid cells over which we assist to the appearance of phenotypic or biochemical abnormalities like albinism.
