Influence of the production performance of Festuca arundinacea cv. Qiancao No.5 in different ecological condition of Guizhou Province

In order to explore the effect of different ecological conditions on production performance of Festuca arundinacea cv. Qiancao No.5 in Guizhou, the difference of production, varieties resistance and nutritional quality between Qiancao No. 5 and F. arundinacea cv. Johnston were studied in five different ecological conditions of Guizhou for two consecutive years. The results showed that: 1) With the altitude increasing, the yield of Qiancao No.5 and Johnston showed a trend of decrease among 5 pilots, especially in Weining pilot that has the highest altitude were (highly) significant lower than the other pilots. And the yield performance of Qiancao No.5 and Johnston were better in Dushan and Guiyang pilots where altitude are relatively low. 2)The yield of Qiancao No. 5 were extremely significant (P<0.01) higher than that of Johnston in each pilot. Thus, the production performance of Qiancao No.5 were better than that of Johnston. 3)The comprehensive resistance of Qiancao No.5 was better than Johnston, and whose EE content was extremely significant (P<0.01) higher than that of Johnston on the nutritional quality. Therefore, Qiancao No.5 was worth promoting production in theory because of its higher production performance, better comprehensive resistance and nutritional value than those of Johnston.
