摘　　要：应用信息熵理论对13个甘蔗品系的7项农艺性状和6项工艺性状指标进行综合评价。结果表明:根据信息熵理论计算出各评价性状的熵权(即权重)与专家依靠经验评判确定的权重大小趋势一致;参试材料的综合评价结果与实际表现一致;认为选育甘蔗优良品种,应对熵权值大的性状,如蔗糖产量、甘蔗产量、有效茎数、蔗糖分等加大选择强度,熵权值小的性状如重力纯度等可从轻考虑。信息熵理论应用于甘蔗品种综合评价,在一定程度上能克服传统综合评价方法的局限性,从而提高评价结果的可靠性和客观性,可为甘蔗品种选育提供新的思路和方法。Seven agronomic characters and 6 industrial characters of 13 new sugarcane lines were generally evaluated by information entropy theory. The results showed that entropy weight values were determined in accordance with the weights of experts on experience; integrated evaluation results were correspond to the actual performance of the sugarcanes. Suggestion on breeding fine sugarcane varieties was focused on large entropy weight values of sugarcane characters, such as sugar yield, cane yield, effective stalks number, and sugar content. Whereas, small entropy weight value of sugarcane characters, such as gravity purity was in indifference. The integrated evaluation of sugarcane varieties by information entropy could overcome the limitations of traditional evaluation methods to improve the reliability and objectivity of evaluation results.
