Comparative performance of plants derived from cuttings and microtubers (in vitro tubers) of the four commercial potato (Solanum tuberosum L.) cultivars namely Spunta, Atlantic, Kennebec and Russet Burbank were evaluated on tuber weight per plant and tuber the screenhouse and field conditions. The analyses of variances for tuber weight per plant under the screen-house condition indicated that the main effects of starting material (M), cultivar (C) and interaction effects (M X C) were significant at P0.05). While those for tuber number per plant under the field condition all of the main effects were not significant. It was found that microtuber-derived plants produced higher yield than cutting-derived plants both under the screen-house and field conditions for all cultivars except Russet Burbank.
