摘　　要：粤选1号匍匐翦股颖新品系是从以匍匐翦股颖(AgrostisstolonifersL.)品种Penncross建坪的老果岭中分离,经系统选育而成的一个新品系。通过营养繁殖建植的粤选1号匍匐翦股颖新品系果岭草坪,与对照品种Penncross比较,新品系植株蔓延较慢,但分蘖性能极强,有利于快速成坪。成坪后,新品系果岭草坪密度、盖度、色泽、质地均优于Pencross,生物量明显高于Penncross,而春季的垂直生长速度显著低于Penncross。6月份原品种草坪明显发黄,生长停滞。新品系适宜于高尔夫果岭和发球台草坪建植。Agrostis stolonifera new strain Yue Xuan No.1 was derived from Penncross -cultivar in old green. This paper reported the turf character of creeping bentgrass new strain Yue Xuan No.l through vegetative propagation for golf greens. The results indicated that the new strain has strong tiller ability to form dense turf while the original cultivar Penncross has strong spreading ability. In spring, the turf quality index such as texture, color, covering of new strain was better than that of Penncross. The above biomass of new strain was higher after mowing to putting green height and the new strain has low erect growth rate overall in early spring. The green-turf of Penncross yellowed and has low growth rate in June. The new strain was invaluable for golf greens and tees.
