초록

본 연구는 한국잔디 신품종 '그린에버'(품종보호출원 2014-02)의 특성을 연구하기 위해 수행되었다. '그린에버'는 한국에서 수집한 100개의 자생 한국잔디에서 선발 육종된 품종이며 유전자 분석을 통해 '안양중지', '동래고려지'와 품종의 차별성을 확인하였다(1.48 kb with OPC14 and 1.05 kb with OPD5). '그린에버'의 형태적 특성 평가결과 잔디의 초장($6.8{\pm}0.5cm$), 엽폭($2.0{\pm}0.1mm$), 최하위 엽까지의 높이($1.9{\pm}0.1cm$) 및 종자의 길이($3.0{\pm}0.1mm$) 등은 금잔디의 특성을 띠는 것으로 분류되었으며, 형태적 특성은 '동래고려지'와 유사하였다. 골프장 페어웨이 관리 조건에서 '그린에버'의 잔디 품질, 밀도, 클로로필 등은 '안양중지' 및 '동래고려지' 보다 뛰어난 것으로 조사되었으며 특히 조사기간 동안 그린에버의 밀도는 '안양중지' 및 '동래고려지' 보다 탁월하게 높은 수준을 유지하였다. 향후 '그린에버'의 내한성, 내마모성 등 다양한 환경적응성이 검증된다면 골프장 페어웨이, 티잉그라운드 및 정원 등에 널리 활용될 수 있을 것으로 기대된다.

This study was performed to study characteristics of new zoysiagarass cultivar 'Green Ever' (Plant Variety Protection Application no. 2014 - 02). 'Green Ever' was developed by selection breeding among 100 native zoysiagrasses collected in South Korea. 'Green Ever' showed specific bands (1.48 kb with OPC14 and 1.05 kb with OPD5) which were distinct from 'Anyang Joonggi' or 'Dongrae Koryogi' in RAPD analysis. 'Green Ever' was classified as Z. matrella in morphological evaluations including plant height ($6.8{\pm}0.5cm$), leaf width ($2.0{\pm}0.1mm$), height of lowest leaf ($1.9{\pm}0.1cm$) and seed length ($3.0{\pm}0.1mm$), which was similar with morphological characteristics of 'Dongrae Koryogi'. Turf quality, shoot density and chlorophyll content of 'Green Ever' were higher than them of 'Anyang Joonggi' and 'Dongrae Koryogi' under intensive management such as fairway on golf course, especially shoot densities of 'Green Ever' were excellent higher than 'Anyang Joonggi' and 'Dongrae Koryogi' during experimental periods. It could be extensively used in fairway, teeing ground of golf courses and landscape garden after further study about various environmental adaptabilities such as winter kill, wear tolerance etc.
