 note = {'Fuyuhikari', a lettuce cultivar resistant to big-vein disease, was developed at the National Institute of Vegetable and Tea Science. It was selected from the progenies of a 'Thompson' × 'Cisco' cross. 'Thompson' is a resistant cultivar, but has a less acceptable appearance and head conformation. 'Cisco' is an elite cultivar for use in winter production in Japan, but is susceptible to the disease. Seeds of the F_3 generation were obtained from about 200 F_2 plants grown in a greenhouse. F_3 plants (14 to 21 plants per line) wore then grown in an infested field, and screened for big-vein resistance and good appearance. Self-pollination and selection were repeated to produce an F_6 line, 'Retasu Ano 2 Go'. The line was self-pollinated repeatedly until F_9 seeds were obtained. The line was then released as 'Fuyuhikari'. 'Fuyuhikari' is more resistant to lettuce big-vein disease than the resistant cultivar 'Logic', which has been used in infested lettuce fields in ,Japan. The yield and quality of 'Fuyuhikari' are equivalent to those of 'Logic', and the yield of 'Fuyuhikari' is higher than that of 'Cisco'. 'Fuyuhikari' grows well at cooler temperatures and is therefore suitable for winter production in Japan. Lettuce plants are grown under plastic tunnels in winter, and it is necessary to prevent the tunnel temperature from becoming too high because high temperatures promote vertical elongation of the heads of 'Fuyuhikari'. Thus, growers should open and close the sides of the tunnels daily or keep them slightly open. The resistance of 'Fuyuhikari' is not perfect, so growers should control the vector by means of soil sterilization or chemicals such as thiophanate-methyl or chlorothalonil.},
