In environments where water is limited, genetic improvement of a crop for drought resistance is an economically attractive option (Blum 2002). However, despite the large resources committed to soybean breeding, progress in improving drought resistance has been slow for a number of reasons.

Because of low heritability of yield under stress and inherent variation in the field, such selection programs are expensive and slow in attaining progress. The objective of this paper is to review the current knowledge in physiology and molecular genetics which have implications in breeding for drought resistance in rice. of modern cultivars with strong drought tolerance. Jongdee, Pantuwan, Fukai, and Fischer (2006) stated that rice varieties that respond well to favorably watered conditions can be developed for improved yield under drought stress if there is early selection for yield under both drought and well-watered conditions.

Phenotyping for drought tolerance of crops in the genomics era. Drought tolerance is the ability to which a plant maintains its biomass production during arid or drought conditions. Some plants are naturally adapted to dry conditions, surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. Other plants, specifically crops like corn, wheat, and rice, have become increasingly tolerant to drought with late-season drought were 45–50% and 15–20% for the upper and middle terraces, respectively. Thus, the target of our breeding program is the development of cultivars with tolerance of late-season drought. 2.2. Developing methods to select for drought tolerance in rainfed lowland rice.
