Abstract

Turfgrass survival and ocurrence of brown patch disease during summer season were investigated the forty six cultivars of cool season grasses in 6 species, popularly used in golf courses in Korea. Ocurrence of brown patch disease was evaluated two times in July. The percentage of turfgrass survival was investigated on Aug. 20 and on Sep. 20 in 2010. There were significant difference for the percentage of turfgrass survival and brown patch disease occurrence among cultivars. Brown patch disease caused by Rhizoctonia spp. and Pythium aphanidermatum with rDNA ITS were showed most susceptible in creeping bentgrass (Agrostis palustris Huds) cultivars and chewings fescue (Festuca rubra var. commutata Gaud) cultivars. The percentage of turfgrass survival during August to September was showed lower creeping bentgrass cultivars and chewings fescue cultivars than another cultivars. Among of 20 cultivars in Kentucky bluegrass (Poa pratensis L.) species were showed highest survival in cultivars of "Nuglade", "Cabernet", "Midnight II" and "Beyond". 6 cultivars of Tall fescue (Festuca arundinacea Schreb) were showed highest survival in cultivars of "Double sentry", "Inferno", and cultivars of "Accent II" in Perennial ryegrass (Lolium parenne L.) species.

한지형 잔디 6종류의 45품종에 대하여 여름철 갈색마름병의 발생과 잔디생존율을 평가하였다. 갈색마름병의 발생율은 7월에 2회 조사를 하였으며, 잔디생존율은 8월과 9월사이에 조사를 하였다. 여름철 갈색마름병의 발생율과 잔디생존율에서 잔디종류별 품종 간에 통계적인 유의성이 차이가 크게 나타났다. rDNA ITS 동정에 의한 갈색마름병원균인 Rhizoctonia spp. 와 Pythium aphanidermatum에의한발병율은 Creeping Bentgrass 품종과 Chewings fescue 품종이 가장 약하였다. 잔디의 생존율도 Creeping Bentgrass 품종과 Chewings fescue 품종이 가장 약하였다. Kentucky bluegrass종은 20 품종 중 "Nuglade", "Cabernet", "Midnight II" 및 "Beyond" 품종이 생존율이 가장 좋았고, Tall fescue 종은 "Double sentry"와 "Inferno" 두 품종에서 생존율이 가장 좋았으며, Perennial ryegrass 종은 2품종 중 "Accent II" 품종이 생존율이 가장 높았다.
