| Abstract |
Sixteen bread wheat cultivar and lines were evaluated in two experimental at Shandaweel Agric. Res. Sta., Sohag governorate, during 2004/2005 and 2005/2006 growing seasons in a randomized complete blocks design (RCBD). Results indicated highly significant difference between genotypes in; days to heading, plant height, 1000 kernel weight, number of spikes/ m2, grain yield under control and natural conditions and their susceptibility to the infestation by cereal aphids. The data revealed that the early heading date genotypes harbored less number of cereal aphids and also the genotypes which possessed high number of cereal aphids gave slight 1000 kernel weight. Grain yield under aphids infestation ranged from 12.34 to 18.07 with an average of 15.59 (ard./fed). The highest grain yield was obtained by wheat genotypes no. 1, 16 and 8, under natural aphids infestation and control. The losses of grain yield ranged from 4.24% to 21.89% with an average of 9.38 %. Wheat genotypes, varied in their susceptibility to the infestation by cereal aphids and can be arranged in four groups, included one genotype (no. 1, Giza 168), was moderate resistance (MR), seven genotype (no. 3, 7,10,11,14, 15 and 16), were low resistance (LR). Meanwhile, seven genotypes (no. 2,4, 5,8,9,12 and 13), were susceptible (S) and attracted high numbers of cereal aphids. On the other hand, genotype no. 6 was found to be highly susceptible (HS) and harboured high number of cereal aphids. In terms of the genotypes (no. 8,9 and 11), (2) and (1 and 2) harboured the lowest number of R. padi, S. graminum and R. maidis respectively. Highly significant positive correlation.
