Summary The field performance of 23 cultivars exposed to various tissue culture regimes was evaluated in the presence of appropriate controls. There were significant differences between cultivars but more importantly there were significant interactions between cultivar and treatments. The largest interaction effect was consistently clones x field vs micropropagated seed tubers and was found to be highly significant ( P < 0.001) for all variates examined. In general, there was little agreement between the performance of cultivars when grown from explant‐derived seed tubers and when they were grown from field‐produced seed. This study demonstrates the potential problems associated with the phenotypic selection of tissue culture derived material in a potato breeding programme.
