- ... The English grain aphid, Sitobion avenae (F.), is a destructive insect pest of wheat. In this study, wheat germplasm was evaluated for resistance and tolerance to English grain aphid infestation. Except for spikelet number/spike, the 1,000-kernel weight, spike weight, grain weight/ spike, and sterile spikelet number/spike of infested plants were all significantly impacted by English grain aphid in ...
