미홍은 "단홍적축면"과 "뚝섬적축면"을 교배하여 육성한 추대가 늦고, 엽색이 매우진한 적축면 잎상추 품종이다. 기존 같은 type의 품종보다 추대가 늦은 중만생 품종이며, 적색발현이 좋아, 안토시안닌 함량이 28.9 mg/100 g으로 "뚝섬적축면"보다 10배이상 많았으며 수확 후 4℃ 수식 이미지에서 3주간 이상 저장이 가능하였다. 재배적기는 연중재배가 가능하나 시험재배 결과 평난지에서는 봄, 가을에 고랭지에서는 여름재배가 가능하
A new red leaf lettuce (Lactuca sativa L.) cultivar, "Mihong" which has late bolting and deep red leaf color was developed from a cross of "Danhongongchukmyeon" (deep red but early bolting and low yield) and "Hajicheongchukmyeon" (late bolting and high yield). The selection and breeding of advanced lines were done by pedigree method during 2000-2006. The advanced lines were evaluated for yield and adaptability in Korea (Gangwon, Kyunggi, Chungbuk, Kyungnam, Jeonnam, Jeonbuk, and Jeju) from 2007 to 2008. The "Mihong" has gray seed color, traverse elliptic leaves and deep red color. Compared to "Dukseomjeokchukmyeon", marketable yield of "Mihong" was higher by 2% (at 291 g per plant) as a 17.3 ton/ha, but with particularly improved good expression of deep red leaf color in high temperature cultivation in the field. The shelf-life of "Mihong" was three weeks longer than "Dukseomjeokchukmyeon" at 4℃. The amount of anthocyanin content of "Mihong" were higher than with "Dukseomjeokchukmyeon" at 28.9 mg/100 g. Especially the degree of leaf hardness in "Mihong"showed 26.9 kg/cm2 compared to "Dukseomjeokchukmyeon" therefore, its taste is better, more crispy, and sweeter than "Dukseomjeokchukmyeon" This new cultivar "Mihong" can be cultivated in all year around even if summer time cultivation.
