Sunflower is a valuable crop in dry conditions already removed on poor soils without irrigation. Sunflower is considered well-adapted to drought, although systematic analyses of the physiological bases of it, and purposeful attempts to breed for greater drought tolerance are still limited. Cropmodellers and geneticists have developed a vision of their roles in plant breeding from their own perspective. However, to improve breeding efficiency, interdisciplinary collaboration becomes increasingly important. Opportunities for collaboration between crop modellers, ecophysiologists and geneticists are explored in this article, to propose powerful tool to resolve genotype x environment interactions. Several views of the integration of physiological responses will be discussed. The first looks at basic responses and considers how linkages can be strengthened by genotype or management (e.g., early sowing). The second introduces simulation modelling as a way to study genotype x environment interactions. The article focuses on significant progress to the study of sunflower and to the integration of knowledge to assist plant improvement and crop management.
