| 520 | _aPhysiology has three main applications within breeding. One is to improve our understanding of the physiological processes that limit yield so as to identify mechanisms for potential genetic modification. Secondly, based on the understanding of yield limiting mechanisms, to identify morphological and physiological traits that when introgressed into improved backgrounds may permit expression of higher yield. A third application is to develop screening protocols using physiological measurements that assist with the identification of physiologically superior lines among early generations and/or advanced materials such that the efficiency of selection is increased. This paper will address examples of how each of these objectives is being carried out within CIMMYT's wheat program. Namely, (i) work aimed at understanding the physiological basis of superior yield and biomass associated with the Lr19 translocation from Agropyron elongatum. (ii) Screening and pre-breeding work aimed at identifying and introgressing morphological traits into high yielding backgrounds with the idea of improving both source and/or sink potential. (iii) Evaluation of physiological traits such as stomatal conductance, canopy temperature depression, and spectral reflectance to establish their association with yield and their potential application as rapid screening tools. | ||
