The reproductive development and yield of two local wheat varieties were evaluated during normal and late cropping seasons. Regardless of cropping season, both varieties had similar final height, yield and reproductive development but differed significantly in spike length. Late planting resulted in shorter plants, extended vegetative growth, less number of grain per spike, higher percentage of light grains, lower 1000-seed weight, and remarkable reduction in grain yield. The effect of cropping season x variety interaction on plant height, phenological stages, yield and yield components was not significant.
