九种黑麦草品种坪用性状的遗传差异研究

Genetic Differences of Nine Ryegrass Varieties Turf Characteristics

对已有的9个黑麦草品种作为草坪草品种(凯蒂沙、庆典、畅想、多福、邦德、爱神特、卡特、神枪手、爱森特)于2003—2005年进行了品种比较试验,通过对其出苗期、成坪期、绿度、密度、叶片质地、均匀性、综合评定等指标的测定表明,凯蒂沙、爱神特、卡特3个黑麦草品种的草坪性状表现比较好,适合长沙地区冷季型草坪,由于其再生能力强、生长速度快,适宜在广场、公园等一些重要地点作为补播、交播优良草种使用推广。

In order to find a variety of cool season turfgrass in Changsha. The experiment comparied a test in year 2003 to 2005 with 9 ryegrass varieties （Katisa, Celebration, Pamper imagination, Dolford, Bond, Accent, Carter, Sharpshooter, Assent）, which were evaluationed measurement index as the lawn through period of emergence, turfmature stage, green degree, density, leaf texture, homogeneity, comprehensive evaluation. The result showed that the lawn characteristic of Katisa, Accent, Carter were well, and can adapt to the cool season turf in Changsha, because of the strong recycled ability, and quick grow speed , so those grass can be used to overseeding and reseeding in garden, public square, and so on.
