The relationship of yield in spring wheat ( Triticum aestivum ) with its components and the morphological structures above the flag leaf node which contribute to the photosynthetic area were studied under both field and greenhouse conditions. Five varieties, with the F 1 , F 2 , and backcross progenies of a complete diallel set of crosses between them, were considered. Ear length, flag leaf sheath length and flag leaf breadth influenced yield and its components significantly. Ear number per plant was the most important component in determining yield per plant.
