| Abstract: | The experiment was conducted to investigate the disease index and the average disease grade of sugarbeet Rhizomania by ocular estimation method.Through the district experiment in 8 different regions in Xinjiang from 2003 to 2004,the results showed that seven sugarbeet strains were as the middle-resistant,the disease index was from 31.2 to 38.9,and the average disease grade was from 1.51 to 2.0;one of them was as the high susceptible,its disease index was 62.4 and the average disease grade was 3.1.The mean root yield of total seven lines for two years had no significant differences,the sugar content was 15.2%-16.1%,and the sugar yield was increased up to 1.9%-11.6% in comparison with CK(KWS5075). |
