A new cultivar of lettuce (Lactuca sativa L.) with wrinkled traverse elliptic and deep red leaf, ‘Gohong’ which has late bolting and high yield was developed from a cross between ‘DL1672’ with deep red leaf color and ‘Cheongchima’ with late bolting and high yield. The cross and selection for advanced lines had been done by the pedigree method from 2005 to 2010. The advanced lines were evaluated for yield and adaptability at several locations (Gangwon-do, Gyeonggi-do, Chungcheongbuk-do, Jeollabuk-do, Gyeongnam-do,and Jeju-do) in Korea in 2010. The ‘Gohong’ has gray seed color and traverse elliptic leaves. The type of matured stage is early and medium leaf lettuce. The shelf-life of ‘Gohong’ was four weeks longer than ‘Dukseomjeokchukmyeon’ at 4℃. The anthocyanin content of ‘Gohong’ was higher than that of ‘Dukseomjeokchukmyeon’ as a 7.5 mg/100 g. The bitter sesquiterpene lactones and latucin+8-deoxylactucin+lactucopicrin (BSL) content of ‘Gohong’ was lower than that of ‘Dukseomjeokchukmyeon’ as a 5.4 ug/g in dry weight.
Compared to ‘Dukseomjeokchukmyeon’, marketable yield of ‘Gohong’ was higher by 12% (at 331 g per plant) and ‘Gohong’ has particularly improved expression of red leaf color in high temperature cultivation in the field. Furthermore, its taste is better, more crispy,and sweeter than those of ‘Dukseomjeokchukmyeon’. So we recommend that new cultivar ‘Gohong’ can be suitable for cultivation in spring and fall season.
