Abstract: The turf quality of 52 hybrids of 14 Zoysia cross combinations were evaluated by density, leaf width, tactility, uniformity, leaf color, green period and rust resistance. The results showed that:The turf quality was improved distinctly with 27 hybrids exceeding their parents or one of them in the total fraction of turf quality, and the other 25 hybrids exceeding their parents in one or more characters. Cultivars 18-1, 22-2, 31-3, 37-1, 223, 40-5, 40-8, 40-2 and 18-4 performed very well. Among them 18-1 was the best, whose turf quality exceeded Z.matrella. The turf quality of other hybrids surpassed Zoysia japonica Steud. cv. Lanyin No. 3.

摘要: 评价密度、叶宽、触感、均一性、叶色、青绿期及锈病抗性七个指标,对结缕草(Zoysia Willd.)属四个种所组成的14个杂交组合中52个杂交后代的坪用价值。结果表明:杂交后代坪用价值得到了明显的改良,共有27个后代的坪用价值综合得分高于双亲或双亲之一,另有25个后代在某一个或某几个性状超过双亲;坪用价值较高的优良杂交后代共有9份,分别为18-1、22-2、31-3、37-1、22-3、40-5、40-8、40-2和18-4,其中18-1表现最优,其坪用价值超过了马尼拉;其它杂交后代坪用价值亦超过了“兰引3号”结缕草。
