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.
