충청남도농업기술원 화훼연구소에서 노란색 계통의 국화 (Chrysanthemum × morifolium (Ramat.) Hemsl.) 품종의 ‘마 루볼(Maru Ball)’을 육성하였다. ‘마루볼(Maru Ball)’ 품종은 노란색 반겹꽃 특성을 갖는 모본 ‘G05-180-01’을 자연방임하여 확보한 자원을 기반으로 선발되었으며, 연차별 생육 및 개화 특성 검정을 거쳐 최종 선발되었다. ‘마루볼(Maru Ball)’은 옆으 로 넓게 자라는 편구체 초형을 보이며, 설상화의 화색은 RHS 색표 기준 Yellow 14A에 해당하였다. 개화는 자연일장 조건에서 9월 25일경 시작되는 중생종 특성을 나타낸다. 주요 생육 형질로 는 평균 화경 3.6cm, 본당 착화수 601.9개, 설상화 수 64.0개, 초장 21.0cm가 확인되었으며, 엽색은 Green 138B 수준의 녹색 을 가졌다. ‘마루볼(Maru Ball)’은 대조 품종인 ‘Smile Ball’과 비교하였을 때, 초형, 개화시기 및 착화량에서 뚜렷한 차이를 보였다. 화단 및 도로변 조경용 식재로 활용성이 높아 보이며, 안정적인 생육과 상품성을 바탕으로 화훼 재배 농가에서 새로운 소득 작목으로 기여할 수 있을 것으로 기대된다.

A new garden chrysanthemum cultivar, “Maru Ball” (Chrysanthemum × morifolium (Ramat.) Hemsl.), was developed at the Flower Research Institute of the Chungcheongnam-do Agricultural Research and Extension Services. The cultivar originated from internal breeding material and was selected through multi-year evaluations emphasizing agronomic performance and ornamental traits. “Maru Ball” is characterized by a spreading, low-mounding growth habit and semi-double capitula with yellow ray florets corresponding to RHS Yellow 14A, while the foliage color corresponds to RHS Green 138B. Quantitative phenotypic assessment revealed an average flower diameter of 3.6 cm, 601.9 flowers per plant, 64.0 ray florets per capitulum, and a mean plant height of 21.0 cm. Compared with the reference cultivar “Smile Ball,” “Maru Ball” exhibits a substantially wider canopy, averaging 57.7 cm in width, and produces slightly larger capitula with a mean diameter of 3.6 cm. Although the number of ray florets per capitulum is lower (64.0) than that of “Smile Ball” (192.9), overall flower production per plant is markedly higher, averaging 601.9 blooms compared with 350.4 in the reference cultivar. Under natural photoperiod conditions, flowering begins in late September, approximately ten days earlier than “Smile Ball.” The cultivar produces basal shoots without pinching, maintains stable vegetative growth during summer, and exhibits strong overwintering ability, indicating broad environmental adaptability. Owing to its prolific flowering, low-mounding canopy architecture, and stable field performance, “Maru Ball” is expected to have high ornamental value for flower beds, borders, roadside plantings, and container production, with strong potential for commercial floriculture and landscape applications.
