Abstract
The physiological approach to improved drought resistance is reported to have five critical stages, which are described: (1) development of a hypothesis concerning the potential contribution of a particular trait, (2) search for genotypic variability for the trait, (3) development of a rapid and efficient screening method, (4) elucidation of the mode of inheritance of the trait and selection of an appropriate breeding method to incorporate it into agronomically superior types and (5) documentation of a strong causal relationship between high values of a trait and improved drought resistance. The performance approach, where direct selection is carried out under water-stressed conditions, is discussed under the following headings: (1) utilizing genetic diversity: population breeding, (2) selection and testing and (3) application of environmental characterization.
