Management of breeding programs for wheat will be more effective upon availability of knowledge on components determine yield and its components under both normal and heat stress condition. In this study, factor analysis was applied to compare under normal and heat stress in the generative phase for yield and its components of 256 wheat accessions obtained from wheat collection of Iranian Plant Genetic Resources. Integration of factor analysis concepts with molecular, QTL physiological point of view is necessary to interpret the data collected in biological systems. Excessive amount of simplification was suggested to be avoided in the biological data interpretation.
