摘　　要：通过对甜高粱抗倒伏性状(重心高度、茎部鲜重、穗鲜重、茎秆机械强度、根干重)的测定,提出甜高粱倒伏系数,并通过性状相关、通径分析,说明利用倒伏系数评价甜高粱的抗倒能力是可行的。Lodging resistance-related traits （ height of center of gravity, stem fresh weight, spike fresh weight, stalk mechanical strength, and root dry weight）in sweet sorghum were measured. Lodging coefficient of sweet sorghum was proposed in this paper. Correlation analysis and path analysis indicated that it was useful in evaluation of lodging resistance of sorghum.
