전국 골프장의 퍼팅그린용으로 사용되고 있는 크리핑 벤트그래스의 주요품종 및 몇 가지 신품종 등 8개 공시품종들에 대해서 2019년 4월 17일 천룡컨트리클럽 실험포지에 파종 후 가시적 피복률을 1주간 간격으로 8주간 조사하였으며, 공시품종간 피복 속도를 알아보고자 25, 50, 85% 피복률 도달일수를 평가하였다. 크리핑 벤트그래스의 8개 공시품종들 간 가시적 피복률은 파종 후 3주부터 8주까지 모두 통계적 유의성이 나타났는데, ‘Shark’와 ‘Distinction’이 가시적 피복률에서 가장 우수한 품종으로 평가되었다. 다음으로 ‘Penn A-4’는 가시적 피복률이 중상, ‘Penn A-1’는 중간, ‘Declaration’ 및 ‘Penncross’는 중하로 평가되어 이들 품종들은 가시적 피복률이 중간그룹을 형성하였으며, ‘Select’와 ‘T-1’은 가시적 피복률이 가장 낮아 피복 속도가 가장 느린 품종으로 평가되었다. 또한, 각 품종의 85% 피복 도달일수 기준의 피복 속도도 품종간 가시적 피복률과 거의 같은 경향이 나타났는데, 가시적 피복률에서 중간그룹인 ‘Penn A-4’는 중상, ‘Penn A-1’는 중간, ‘Declaration’ 및 ‘Penncross’는 중하로 평가되어 세분되었으나 85% 피복 도달일수에서는 이들 품종들이 모두 중간 그룹으로 같이 평가된 점만 다르게 나타났다. Coverage characteristics were evaluated under main creeping bentgrass (Agrotis stolonifera L.) cultivars used in Korean golf course greens. Eight cultivars of creeping bentgrass (CB) were ‘Penncross’, ‘T-1’, ‘Penn A-1’, ‘Penn A-4’, ‘Shark’, ‘Declaration’, ‘Pure Distinction’ and ‘Pure Select’. Experiment was conducted on a 1m×1m plot with three replication (total plot size=24 m²) of Chunryong country club located in Jincheon, Chungcheongbuk-do, Korea. Weekly coverage rates and required days to 25, 50, 85, and 100% coverage after seeding were measured and analyzed. Significant differences of CB cultivars were observed in weekly coverage rates and required days of the 50, 85, and 100% coverage after seeding. As for the coverage rates, it was 30.0-46.7% (16.7% difference) on 3 weeks after seeding (WAS), 70.0-80.0% (10% difference) on 4 WAS, 83.3-90.0% (6.7% difference) on 5 WAS and 93.3-100% (6.7% difference) on 6 WAS among CB cultivars, respectively. And the number of days it takes for treated CB cultivars to cover up to 85% of plot was 29.7-35.2 days.

신영수(Young Soo Sin),심상렬(Sang Ryul Shim),김재환(Jae Hwan Kim) 한국잡초학회 2021 Weed & Turfgrass Science Vol.10 No.2

2019년 4월 17일 충북 진천군 이월면 소재 천룡골프장 묘포장에 크리핑 벤트그래스 8품종들을 파종하고 그 이후 관행적으로 잔디를 관리하여 생육시켰으며 파종 후 약 1년 5개월 지난 2020년 10월 27일 잔디를 4.0 mm 와 3.6 mm 높이로 깎아 스팀프미터(stimpmeter)를 이용 볼 구름 거리를 측정하였다. 4.0 mm 깎기 높이 시의 크리핑 벤트그래스 품종들간 볼 구름은 ‘Shark’와 ‘Pure Distinction’의 볼 구름이 가장 빠르고, ‘Pure Select’와 ‘Penn A-1’가 그 다음으로 빨랐으며, ‘Declaration’이 중간 빠르기의 볼 구름을, ‘Penn A-4’와 ‘T-1’은 느린 볼 구름 특성을, 그리고 ‘Penncross’는 가장 느린 볼 구름 특성이 나타났다. 3.6 mm 깎기 높이 시에는 ‘Pure Distinction’의 볼 구름이 가장 빨랐고, ‘Shark’, ‘Pure Select’ 및 ‘Penn A-1’이 그 다음으로 빨랐으며, ‘Declaration’, ‘Penn A-4’ 및 ‘T-1’이 중간 또는 중간 이하의 느린 볼 구름 특성을, 그리고 ‘Penncross’는 가장 느린 볼 구름 특성을 나타냈다. 4.0 mm 깎기 높이 시와 비교하면 ‘Pure Distinction’이 ‘Shark’보다 가장 빠른 볼 구름을 보인 것 이외에는 품종들간 거의 유사한 볼 구름 특성을 보였다. Green speed was evaluated of main creeping bentgrass (Agrotis stolonifera L.) cultivars used in Korean golf course greens. Eight cultivars of creeping bentgrass (CB; Agrotis stolonifera) were ‘Penncross’, ‘T-1’, ‘Penn A-1’, ‘Penn A-4’, ‘Shark’, ‘Declaration’, ‘Pure Distinction’ and ‘Pure Select’. Experiment was conducted on a 1 m×5 m plot with three replication (total plot size=120 m²) at Chunryong Country Club located in Jincheon, Chungcheongbuk-do, South Korea. Green speed was evaluated using by the stimpmeter under 4.0 mm and 3.6 mm mowing height on Oct. 27 in 2020, respectively after seeding on Apr. 17 in 2019. Significant differences of CB cultivars were observed in ball roll distance. As for ball roll distance of CB cultivars at 4.0 mm cut, it showed 0.55 m difference with 2.85 m (‘Shark’, the fastest cultivar) to 2.30 m (‘Penncross’, the lowest cultivar) among treated CB cultivars. On the other hand, Pure Distinction (2.80 m) and Pure Select (2.75 m) showed relatively fast ball speed when compared to medium high ball speed with ‘Penn A-1’ (2.70 m), medium low with ‘Declaration’ (2.60 m), low with ‘Penn A-4’ (2.50 m) and ‘T-1’ (2.50 m). In regard of ball roll distance of CB cultivars at 3.6 mm cut, it showed 0.15-0.30 m faster than ball roll distance at 4.0 mm cut. In this time, Pure Distinction was evaluated with the fastest cultivar on 3.10 m while ‘Penncross’ with the lowest cultivar on 2.60 m ball roll distance. On the other hand, ‘Shark’ (3.00 m), ‘Penn A-1’ (2.98 m) and ‘Pure Select’ (2.95 m) showed relatively fast ball speed when compared to slow ball speed with ‘Declaration’ (2.78 m), ‘Penn A-4’ (2.75 m), ‘T-1’ (2.70 m). Considering ball roll distance under 4.0 mm and 3.6 mm cut in this study, ‘Shark’ and ‘Pure Distinction’ were regard as excellent ball roll speed cutivars when compared to relatively high speed cultivars with ‘Pure Select’ and ‘Penn A-1’, relatively low speed with ‘Declaration’, ‘Penn A-4’ and ‘T-1’, and the lowest speed with ‘Penncross’.

본 연구는 연간수득상금형질을 이용한 국내 씨수말 평가시스템을 분석하여 주파기록과의 관계를 구명하고자 수행되었다. 씨수말 당 평균 자마수와 출주수는 각각 34두와 221회였다. 반면에 평균 2세 자마수와 출주수는 각각 9두와 25회였으며, 2세 자마들이 벌어들인 상금은 연간 수득상금의 8.3%였다. 연간수득상금에 대한 자마수와 출주수간의 단순상관계수는 각각 0.922와 0.934, 그리고 자마수와 출주수간의 단순상관계수는 0.985로 매우 높게 나타났다. 씨수말의 검정경력 첫해의 평균 자마수는 6두, 출주수는 17회로 매우 낮았으며, 검정경력에 따른 자마수와 연간수득상금은 매우 밀접한 관계를 나타내었다. 검정경력 4년차에서 40두 이상의 자마수를 확보하는 것으로 나타났으며, 자마수가 증가할수록 평균수득상금지수는 일괄적으로 증가하였다. 자마수가 30두 이하의 씨수말들의 평균수득상금지수는 1.00 보다 낮았으며, 자마수가 10두 이하인 경우에는 0.06에서 0.13의 범위를 나타내어 자마수는 씨수말의 순위 결정에 매우 큰 영향을 미치고 있었다. 주파기록에 대한 육종가와 출주당 수득상금의 상관계수는 다른 형질들에 비하여 가장 높은 -0.524에서 -0.633의 범위를 나타내었다. This study was conducted to analyze demerits of the sire evaluation system using annual earnings and to examine relationship between annual earnings and finish time in home-produced thoroughbred racehorses. The average number of progenies and number of starts per sire were 34 heads and 221 times, respectively. On the other hand, the number of progenies with the average age of 2 years and the number of starts were 9 heads and 25 times, respectively. The earnings of the horses with the age of 2 years accounted for 8.3% of annual earnings. The simple correlation coefficient between the number of progenies and the number of starts in annual earnings were 0.922 and 0.934, respectively. The correlation coefficient between the number of progenies and the number of starts was very high (0.985). The number of progenies and starts of sires for the first year of test career were very low (6 heads and 17 times), and there was very close relationship between number of progenies and annual earnings by the year of test career. The number of progenies was over 40 heads during the first 4 years of test career, and as the number of progenies increased the average earning index increased. The average earning index of sires with less than 30 progenies was lower than 1.00. When the number of progenies was less than 10, the average earning index was in the range of 0.06~0.13, indicating that the number of progenies affects much for determining the ranking of sires. The correlation coefficient between breeding value for finish time and annual earnings per start was very high(-0.524~-0.633) compared with other traits.
