The objective of this study was to formulate a management system for improving early Quebec tomato yields through the use of polyethylene row tunnels and the screening of three tomato genotypes for their performance under a tunnel system of growing. / Three tomato (Lycopersicon esculentum Mill.) cultivars, Springset (early, cold-tolerant), Celebrity (standard), and Hope No. 1 (early, heat-tolerant), were grown under clear or white perforated polyethylene row tunnels that were either vented ten days prior to anthesis to maintain temperatures below 30$ sp circ$C or nonvented. Controls had no tunnel treatment. / Springset had the highest harvest index and subsequent highest early yield. Celebrity had the highest total yield. Hope was not suited to producing early yield under the frequent low temperature conditions occurring during the spring in Quebec. Tunnels did not improve early or total yield. / Further research is required before tunnels can be recommended for producing early tomatoes in Quebec.
