Abstract

It is important for genetic resources to collect and identify in native medium-leaf type zoysiagrasses species distributed in Korea. This study was conducted to investigate morphological variation and characteristics of native medium-leaf type zoysiagrasses from coastal, island and inland regions in Korea. Among them, 75 collected lines was confirmed to have various morphological variations, accessions were classified into 2 main based group coastal and inland regions by morphological characteristics and site environment. Group I included Z. sinica type, this group showed 3.7 mm in leaf width, 29 in number of seed per spikelet and 5.0 mm in seed length. Group II included Z. japonica type, this group showed 4.4 mm in leaf width, 42 in number of seed per spikelet and 3.5 mm in seed length. There is a need for additional research on growth characteristics and the molecular level for the introgressive hybridization between species which confirmed that cross-pollination is possible due to protogyny. The individuals showing variations should be preserved as valuable genetic resources for the expansion of variations in zoysiagrasses, and the results of this investigation on the genetic resources collected will be highly valuable in breeding high quality turfgrass.

우리나라는 다양한 자생 중엽형 한국잔디 유전자원이 널리 분포하고 있으며, 유전자원 연구에 있어서 유전자원의 수집 및 확인이 중요하다. 본 연구는 해안 및 도서, 내륙지역에 자생하고 있는 중엽형 한국잔디를 지역별로 수집하여 형태적 특성 및 입지환경에 따른 변이를 알아보고자 수행되었다. 수집된 75개의 중엽형 한국잔디는 입지환경에 따라 다양한 형태적 변이가 존재하는 것을 확인하였고, 크게 해안(I군)과 내륙(II군)지역으로 두 개 그룹으로 나뉘었다. I군은 엽폭 3.7 mm, 소수당 종자수 29개, 종자길이 5.0 mm으로 갯잔디형 특성으로 나타났고, II군은 엽폭 4.4 mm, 소수당 종자수 42개, 종자길이 3.5 mm로 들잔디형으로 정확한 종간교잡의 정도를 파악하기 위해서는 추가적인 생육특성 및 분자생물학적 연구가 필요하다고 생각되었다. 상기 변이를 보이는 개체들은 앞으로 한국잔디의 변이를 확대하기 위한 귀중한 유전자원으로 보존가치가 높으며, 고품질 잔디육종을 위한 귀중한 자료로 활용가치가 높다고 판단된다.
