[Objective]To elucidate the influence of the main agronomic traits and quality of different sugar beet varieties on sugar yield,and to identify suitable sugar beet varieties for promotion in Ili River Valley,[Methods]a comprehensive analysis of the agronomic traits of 27 sugar beet varieties(lines)was carried out by combining analysis of variance(ANOVA)and grey correlation analysis.[Results]The highest yield of sugar beet was'JTD202'(93 976 kg/hm2),while'HI0064'had a lower yield(93 950 kg/hm2);The top five varieties for yield were in the order of'JTD202'>'HJTD201'>'BTS6870'>'BTS5940'>'BTS4880';'MA3023'performed the highest sugar content of 15.78%,and sugar beet'KUHN4092'had a lower sugar content of 12.09%,and the top five varieties for sugar content were in the order of'MA3023'>'BTS6870'>'XJT9923'>'HI0064'>'KWS0023'.The correlation of each trait to sugar yield was in the order of sugar content>number of leaves>plant height>root perimeter>root head diameter>root length>leaf area per plant>root yield.The main factor affecting sugar yield of sugar beet was sugar content.[Conclusion]In the Ili River Valley,sugar beet varieties'JTD202','HJTD201'and'BTS6870'show high yield,while'MA3023','BTS6870'and'XJT9923'are high-sugar types,and the above varieties are suitable for demonstration and promotion.
