Abstract

The chromosome morphology of two Korean Lactuca (L. indica, L. triangulata) is reported herein. The chromosome number and karyotype of a naturalized plant, L. scariola are reported for the first time. The basic chromosome number was x = 9. Polyploid forms were not recorded. The karyotypes of L. indica, L. scariola, and L. triangulata were 2 n = 18 = 2 m+ 7 sm, 2 n = 18 = 1 m + 6 sm+ 2 st, 2 n = 18 = 2 m + 5 sm+ 2 st, respectively. Both L. indica and L. triangulata had satellites at the ends of their short arms. The haploid genome lengths of L. indica, L.scariola, and L. triangulata were $56.3{\mu}m$, $35.3{\mu}m$, and $72.5{\mu}m$ respectively. Each chromosome length of naturalized L. scariola was $2.7-5.2{\mu}m$; the smallest among Korean Lactuca. The chromosome lengths of L. indica and L. triangulata were $4.7-7.6{\mu}m$ and $2.9-7.9{\mu}m$, respectively. The karyotype of L. scariola differed from that of L.indica and L.triangulata both of which belong to sect. Tuberosae. Therefore, L. scariola is thought to belong to sect. Lactuca subsect. Lactuca.

본 연구에서는 왕고들빼기속 (Lactuca) 중에서 한국에 자생하는 왕고들빼기 (L. indica)와 두메고들빼기 (L. triangulata)의 체세포염색체수와 핵형을, 귀화종인 가시상치 (L. scariola)의 체세포염색체수와 핵형을 처음으로 조사하였다. 체세포염색체의 기본수는 x = 9이었고 염색체 배수화 현상은 나타나지 않았다. 염색체 조성을 조사한 결과 왕고들빼기는 2n = 18 = 2 m + 7 sm, 가시상치는 2n = 18 = 1 m+ 6 sm + 2 st, 두메고들빼기는 2n = 18 = 2m + 5 sm + 2st로 나타났고, 왕고들빼기와 두메고들빼기의 경우 염색체의 단완 말단에 부수체가 존재하였다. 왕고들빼기, 가시상치, 두메고들빼기의 반수체 게놈의 길이는 각각 $56.3{\mu}m$, $35.3{\mu}m$, $72.5{\mu}m$로 나타났고, 각 염색체의 크기는 귀화종인 가시상치가 $2.7-5.3{\mu}m$로 가장 작았으며 왕고들빼기와 두메고들빼기는 각각 $4.7-7.5{\mu}m$, $5.0-8.0{\mu}m$로 비슷하였다. 가시상치의 핵형은 sect. Tuberosae에 속하는 왕고들빼기, 두메고들빼기와 차이를 보인 반면, sect. Lactuca, subsect. Lactuca에 속하는 분류군의 핵형과 유사한 것으로 조사되었다.
