Yield and resistace of new tall fescue strains in the Guizhou Province

An experiment with random complete block design was conducted to compare the yield and resistance of new tall fescue (Festuca arundinacea) strains which was bred during 2007 to 2010. This study showed that the fresh and dry yield of DaFang strain was much higher than that of the control, and were up to 87 825 kg/ha and 15360kg/ha at the second year when plant height was 30 to 40 cm. They increased by 14.37% and 26.88% when compared with the control trains of Fawn. Seed yield of DaFang strain was 856.5 kg/ha, and increased by 94.2% when compared with the control strain of Fawn. The survival rate in summer of DaFang strain was 95.95%, and increased by 24.4% when compared to those of the control strain. The heat tolerance and drought resistance of Dafang strain was better than that of the control strain of Fawn. The comprehensive assessment suggested that Dafang strain performed well in the Guizhou Province.
