Abstract

This study was carried out to develope new zoysiagrass cultivars 'JangsungChorok' (Application No. :2013-3) and 'JangsungSaetbyeol' (Application No. :2013-4). One hundred and one genetic resources were collected at Jangsung Gun area from 2010 to 2011. Among the collected lines, CY6097 (JangsungChorok) and CY6069 (JangsungSaetbyeol) showed superior performance in spring green up and growth rate. 'JangsungChorok' showed genetically light green leaf color, with medium leaf width (4.4 mm), height from ground to first leaf blade of 3.2 cm and average plant height of 18 cm. Fast recovery rate and early spring green up rate will make this cultivar (JangsungChorok) for efficient sod producer. 'JangsungSaetbyeol' showed genetically dark green leaf color, with fine to medium leaf width of 3.5 mm, height from ground to first leaf blade of 4.3 cm and average plant height of 22.6 cm. Fast recovery rate and early spring green up rate with relatively narrow leaf will make this cultivar (JangsungSaetbyeol) for high sod quality.

본 실험은 한국잔디 신품종 '장성초록'(품종보호출원:2013-3)과 '장성샛별(품종보호출원:2013-4)의 개발에 관한 것이다. 2010-2011년에 국내 잔디 주 생산 단지인 전라남도 장성 지역에서 수집한 101개 유전자원의 특성 평가를 통해 2개 계통을 선발하였다. 선발계통 중에서 CY6097(장성초록)과 CY6069(장성샛별)은 봄철 휴면타파 속도가 빠르고, 초기 생육속도가 우수하였다. '장성초록'은 엽색이 연녹색이며, 엽 너비가 4.4 mm로 중엽형이다. 지면에서부터 첫 번째 잎까지의 높이가 3.2 cm로 낮아 낮게 깎기가 가능하며, 초장 평균도 18 cm로 낮게 자라는 특성을 갖고 있다. 늦가을 휴면진입 속도가 늦어 녹색 보유 정도가 많으며, 봄철에도 타 잔디에 비해 휴면타파 속도가 빠르다. '장성샛별'은 엽색이 진녹색이며, 엽 너비가 3.5 mm로 중세엽 형이다. 지면에서부터 첫 번째 잎까지의 높이가 4.3 cm로 높고, 초장 평균도 22.6 cm로 높다. 봄철 휴면타파 속도가 빨라 조기 수확이 가능하기 때문에 장성잔디 재배 농가에서 고품질 뗏장 생산에 유용하게 활용될 수 있을 것으로 판단된다.
