Abstract

In this study, 241 zoysiagrasses (Zoysia spp.) accessions naturally growing in South Korea were collected in order to investigate the seed morphological traits. One of the goals of this study was to identify the morphological characteristics and variations of zoysiagrass seed. For the 241 zoysiagrasses accessions collected, a total of 41% (99 accessions) was interspecific hybrid zoysia, which showed various types of seed variations different from zoysiagrass species. Most of these hybrids zoysiagrasses were classified into Z. sinica type and Z. japonica type. Group I and II included Z. sinica type, this group showed 30.1 and 17.5 in number of seed per spike and 4.6 and 5.2 mm in seed length. Group III and IV included Z. japonica type, this group showed 59.2 and 45.8 in number of seed per spike and 3.3 and 3.4 mm in seed length. There is a need for additional research on growth characteristics and the molecular level for the interspecific hybridization which confirmed that genetic variation from level of gene flow between the species.

본 연구는 국내에서 자생하고 있는 241개체의 한국잔디를 지역별로 수집하여 종자 형태적 형질을 조사했으며, 한국잔디의 종자 형태적 특성 및 변이를 알아보고자 연구를 수행하였다. 수집된 한국잔디 241개체 중에서 중지가 99개체로 41% 이상이 수집되었으며, 다양한 형태의 종자 변이를 보였다. 크게 갯잔디형과 들잔디형으로 두 개 그룹으로 나뉘었으며, I과 II군은 화서당 종자수가 30.1개와 17.5개, 종자길이는 4.6과 5.2 mm으로 갯잔디형이 포함되었고, III과 IV군은 화서당 종자수가 59.2개와 45.8개, 종자길이는 3.3과 3.4 mm으로 들잔디형 특성을 나타내었다. 정확한 종간교잡의 정도를 파악하기 위해서는 추가적인 생육특성 및 분자생물학적 연구가 필요하다고 판단되었다.
