Abstract: Summer high temperature and humidity seriously impact tall fescue turf quality in northern China. In the past ten years, more and higher turf quality and disease resistance turf type tall fescue cultivars have been released. However, a little is known about their adaptability and differences in Huabei region of China. To evaluate varietal adaptabilities and differences for customer selection, 30 cultivars were tested in Beijing during this five year study. Results showed that turf quality, genetic color, leaf texture and disease resistance were improved in these newer cultivars. Cluster analysis of scoring ratings divided cultivars into three groups of high, middle and low turf quality. Typical high turf quality cultivars included Banshee, Rocket, Fat Cat, Terrier, Essential, Houndog 6 and Cannavaro.

Key words: Turf type tall fescue, Adaptation evaluation, Disease resistance, Cluster analysis

摘要: 华北地区夏季高温高湿影响高羊茅(Festuca arundinacea Schreb.)草坪质量。近10年来,国际上育成了较多综合性状好的抗病性草坪型高羊茅品种,虽然这些品种已在中国市场流通,但对其在华北地区的适应性及品种差异了解的不多,仅限于商品宣传。因此,为比较不同阶段育成品种的差异,方便草坪用户选择品种,在北京对30个草坪型高羊茅品种进行了5年的综合评测。结果表明:新育成品种在草坪综合质量、遗传颜色、叶片质地和抗病性方面总体优于早期育成品种。品种适应性评价的聚类分析结果将参试品种依据草坪质量划分为高中低3个类群,高草坪质量类群的典型品种主要有Banshee,Rocket,Fat Cat,Terrier,Essential,Houndog 6和Cannavaro等。
