Zusammenfassung:	Estival is a heavy crisphead lettuce highly tolerant to bolting under long day growing conditions (more than 13 h). Estival is the first Vanguard-type lettuce released by the Horticultural Research and Development Centre (HRDC) lettuce breeding program of Agriculture and Agri-Food Canada (AAFC), Saint-Jean-sur-Richelieu, Quebec. Very similar in appearance to Summertime, Estival is well adapted to organic soils. Estival is more tolerant than Ithaca (the regional standard) or Summertime to rib discoloration, a physiological disorder caused by high-temperature growing conditions. Key words: Lactuca sativa, crisphead lettuce, rib discoloration, bolting, tipburn, heat stress, organic soil
