Sanborn's conclusion is that very little, if any, advantage is to be gained by separating seed wheat and planting the large kernels. At the Indiana Experiment Station, Latta" conducted experi- ments in which wheat was separated by means of a fanning mill into heavy and light kernels, but impurities and chaffy seed were fanned out of each lot of wheat. The experiments were continued three years, but the separations were made each year from seed that had not been so separated the year before. The average gain from the large seed for three years was bushels per acre. Georgeson/' at the Kansas station, seeded plots of land with (1) light seed weighing 56 pounds per bushel, (2) common seed weighing pounds, (3) heavy seed weighing 63 pounds, and (4) selected seed, obtained b}T picking the largest and finest heads in the field just before the crop was cut, weighing pounds per bushel. Seed was separated each year from wheat not grown from previously selected seed. The average results for three years were as follows:.
