Drought resistance is a complex quantitative trait of the interaction between crops and drought environment， accurate evaluation of drought resistance phenotype is the basis for mining drought resistance genes and exploring drought resistance genetics， it is very important for water-saving and drought-resistant rice breeding. The method system for the evaluation of drought resistance of rice germplasm during whole growth periods in the field has always been a technical problem concerned by drought-resistant breeding workers. Aims at this problem， we exploring and optimizing the conditions for assessing drought resistance based on many years of the evaluation and research of rice drought resistance in the field. The standard technical regulations for drought resistance evaluation in the field of rice germplasm during whole growth periods were summarized and normalized. It mainly includes general requirements， land preparation， the methods of planting， water management， fertilization， prevention of diseases， pests and weeds and drought resistance evaluation， so as to provide technical reference for drought resistance evaluation of rice germplasm during whole growth periods. The technical regulations are 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）.
