摘要： 在旱作与水作条件下，对旱稻抗旱性评价的指标进行了研究，并借引了灰色关联分析法进行了评价指标的筛选。研究结果表明：旱稻抗旱性评价指标对旱作产量的关联顺序是：抗旱指数>抗旱系数>相对株高>综合抗旱力指数>相对结实率>相对出穗日数。利用产量的抗旱指数作为评价旱稻抗旱性是科学的、可行的、实用的。

Abstract: Under upland and paddy cultivation, the appraise index of drought resistance of upland rice was studied and selected the appraise index by applying grey relation analysis. The result showed that the related order about appraise index of drought resistance and upland yield was, drought resistance index > drought resistance coefficient > plant height > synthesize drought resistance index > seed setting rate > heading date. It was scientific, feasible and applied that applying drought resistance index appraise drought resistance.
