SUMMARY As the result of studies on Oscinella frit during the years pro to 1928, it was considered that an attempt might be made to solve economic problem presented by this fly by hybridization of oats, i a resistant variety as one parent. The technique adopted is described and the experimental data show that resistance to attack is an inheritable character (or complex characters), although difficult of precise measurement. Further, shown that agricultural quality and resistance to attack are not in patible. Wet weather conditions during the flight of the fly have a marked effect in limiting the extent of damage to the crop. It is suggested that varietal differences in extent of attack ma due to varietal differences in crude fibre production or depositio silica, both tending to increase the larval difficulties and there for resistance of the plant. I have great pleasure in acknowledging the readiness with w Dr Hunter of the School of Agriculture, Cambridge, has given me benefit of his experience; also, the valuable criticism which Mr J. C. F. Fryer, of the Ministry of Agriculture Pathological Laboratory, Har‐penden, has always placed freely at my disposal.
