Abstract

This study was carried out to develop new hybrid zoysiagrass cultivar 'Seah' (The application no. for cultivar protection : 2014-22). Native zoysiagrasses were collected from south-west seaside of Korea from 2010 to 2011. Artificial crossing was conducted to develop F1 hybrid between Z2011 (Z. sinica) and NM1 (Z. matrella) at plastic house in 2011. Among the progenies, 'Seah' showed fine leaf texture and high shoot density from the space planting plots at field. 'Seah' showed genetically light green color, with fine leaf with 1.8mm and height to the lowest leaf blade was 1.94 cm. Ground coverage rate was slower than medium leaf zoysiagrass (Jung-gi), but plant height of 7.1 cm was the lowest among the compared zoysiagrasses and height to lowest leaf of 1.94 cm was lower than most zoysiagrass, which may allow low mowing height.

한국잔디 신품종 '세아' (품종보호 출원번호:2014-22)는 2010-2011년 한반도 남, 서해안 및 도서지역에서 수집된 잔디 유전자원을 사용하여 인공교배육종으로 작성 되었다. 2011년 형태적으로 구별성이 있는 수집종 Z2011 (Z. sinica) 모본과 NM1 (Z. matrella) 부본 간에 인공교배를 수행하였으며, 2012년 작성된 후대(F1) 중 Space planting을 통해 생육이 우수하고 밀도가 높은 고품질 계통(Z2011xNM1)-2을 선발하였으며, 이를 '세아' 라 명명하였다. 2년간 포장적응 실험을 통해 적응성, 안정성, 구별성을 확인하였으며, '세아'를 신품종으로 출원하게 되었다. '세아' 품종의 특성은 엽색이 연한 녹색이며 엽 너비는 1.8 mm로 세엽이다. 지면에서 첫 번째 잎까지의 높이가 1.94 cm로 낮아 낮은 깎기에 적응도가 높다. 초장도 7.1 cm로 매우 낮은 생육형을 보인다. 생육속도는 느려서 뗏장 생산 효율은 다소 떨어진다고 판단된다. 그러나 줄기 밀도가 높고 세엽형이라 품질이 우수하다.
