In testing inbred lines of corn, it has been the custom of many corn breeders to combine systematically the lines to be compared in a series of comparable crosses. Although the performance of the individual crosses is determined, the inbred line usually is saved or discarded on the basis of the mean of all of its crosses. This necessitates making and testing very large numbers of crosses. In order to determine the feasibility of a less arduous method of testing inbred lines in crosses, comparisons of different. methods of testing inbred lines were made in 1929 and 1930 at the Iowa Agricultural Experiment Station and in 1930 at the Kansas Agricultural Experiment Station. The results are presented in the present paper.
