Tolerance As A Novel Mechanism Of Hessian Fly Control On Wheat, Kirsten E. Roe

Open Access Theses

The effects of Hessian fly (Mayetiola destructor Say) infestation on the putative tolerant wheat line Pioneer ®brand variety 25R78 were investigated at the seedling stage. Measurements, including leaf and tiller number, leaf growth rate, and total leaf lengths were recorded for two time intervals, 16 and 32 days post infestation (dpi). At 16 dpi, total leaf length changes and leaf growth rates were significantly lower for infested tolerant plants versus uninfested plants. No permanent growth effects occurred in the 32-day set. There were no significant differences in change in leaf length and leaf growth rate in infested tolerant plants …
