Two field experiments were conducted at the Experiment and Research Center, Fac. Agric., Moshtohor, Benha Univ., Kalubia Governorate, Egypt, during 2007/08 and 2008/09 seasons, to study the effect of three seeding rates (40, 60 and 80 kg fed-1) on growth, yield and yield components of seven wheat genotypes (Giza 168, Sakha 93, Sakha 94, Gemmiza 7, Gemmiza 9, Sids 1 and Sids 12). The most important results which were obtained from this study were as follows: Gemmiza 7 gave the highest values of flag leaf area, spike length, No. of spikelets spike-1, seed index and grain yield fed-1, Gemmiza 9 gave the highest values of plant height and straw yield fed-1 while, Sakha 94 gave the highest values of No. of tillers plant-1 and No. of spikes/m2 moreover, Sids 1, Gemmiza 7 and Sakha 93 genotypes were earlier heading, respectively compared with other genotypes. The highest values of plant height, No. of spikes/m2, grain and straw yields fed-1were produced by the highest seeding rate (80 kg fed-1). On the other hand, the lowest seeding rate (40 kg fed-1) producing the highest values of No. of tillers plant-1, flag leaf area, spike length, No. of spikelets spike-1and seed index, while No. of days to 50% heading was not significantly affect by different seeding rates. Effect of the interaction between wheat genotypes and seeding rates was significant on No. of tillers plant-1, No. of days to 50% heading, flag leaf area, plant height, spike length, No. of spikelets spike-1, No. of spikes/m2, seed index, grain and straw yields fed-1. Results indicate that No. of tillers plant-1, plant height, spike length, number of spikes/m2 and straw yield fed- had the greatest influence on grain yield fed-1. Flag leaf area, was significantly correlated with grain yield fed-1.
