On the basis of several years' research, 219 turfgrass cultivars belonging to 17 species and 11 genera were introduced and collected. Through systematical observation and evaluation, 27 superior cultivars with good adaptability to the soil and climate of Tianjin were selected, including cold season turfgrasstall fescue, warm season turfgrassbuffalograss and Zoysia japonica. The resource pool of turfgrass including over 200 cultivars were set up. During the research of seed propagation technology of tall fescue, its growth rule in Tianjin was grasped; the best sowing rate, appropriate sowing period and the best harvesting time were determined, which established the good base for the lawn research in Tianjin.
