Abstract: The growth rate was significantly (P<0.01) different among the tested P. pratensis populations. The highest was 05P13 (3.98 mm/d); the lowest was 05P06 (0.12 mm/d). The total tiller number among the tested P. pratensis varied from 38.0 to 161.33 tillers/plant. The rhizome characteristics were divided into 3 groups by cluster analysis method based on rhizome number, rhizome length and rhizome diameter parameters, and the 15 materials were classified by strong, medium and weak rhizome types. Take 8 indices about texture, density, uniformity, color, maturate time, green period, rust disease resistance and heat resistance to comprehensively evaluate turf characters, the results indicated that the maximum comprehensive value evaluated on turf characters included CK1 (4.25) and 05P04 (4.25), the minimum included 05P02 (2.75) and 05P07 (3.13) because of weak rust disease resistance and heat resistance and the others were medium.
