| Abstract: | The field test of the 11 alfalfa materials was carried on in Zhenglanqi Inner Mongolia during March to October 2012. The winter rates, plant height, main stem number, leaf rate, reproducibility and hay yield were compared. The results indicated that： The Radar was the best of the 11 alfalfa materials. Its plant height was 81 cm, the branch number was 475 branches/m, the hay yield was 37277 kg/hm2 , the reproducibility speed was 1.44 cm/d and the winter survival rate was up to 98 %. The following were Caoyuan No. 3, successively Giant and the Algonquin. The Shangdu was a local alfalfa material which ranked the 5th whose indicators were all in the middle or upper level, so it also has cultivated value. |
