Summary

Black spot pigment development in progeny of crosses between potato clones with varying degrees of resistance to black spot, was evaluated using 3 methods, after different periods of storage. All methods were able to separate genotypes based on black spot resistance. Bruise resistant genotypes transferred their resistance to progeny in crosses with a susceptible genotype. Tuber resistance to black spot is varying during 8-9 month storage, according to the method employed. Free tyrosine was consistently associated with black spot pigment development but chlorogenic acid and caffeic acid were not.
