Accurate evaluation of drought resistance phenotype is the basis for mining drought resistance genes and exploring drought resistance genetics. At present, the method system for the evaluation of drought resistance of rice germplasm during whole growth periods in the field has not been reported. Based on many years of the evaluation and research of rice drought resistance in the field, the standard technical regulation for drought resistance evaluation in the field of rice germplasm during whole growth periods is formulated in this paper. It mainly includes application scope, land preparation, the methods of planting, watering, fertilization, weeding and harvest, and drought resistance evaluation index, so as to provide technical reference for drought resistance evaluation of rice germplasm during whole growth periods. The standard technical regulation is applicable to the evaluation of drought resistance during whole growth periods during the winter in Sanya City, Hainan Province (from mid-November to early-April of the next year).
