In plant breeding work it is becoming increasingly evident that a knowledge of the method of inheritance of different morphological and physiological characters is very important for efficient planning of the breeding program. With this information available, it is possible to select the parents most desirable for a cross and to make some estimate as to the size of segregating population needed to give assurance of the recovery of the desired types.

The inheritance of quantitative characters is usually more complicated than the inheritance of qualitative ones, thus making the study more difficult. The cross described in this paper was made to provide material for the study of the inheritance of kernel size which is preliminary to investigations of the relation of this character to test weight per bushel.

The purpose of this study was to obtain more information on the nature of segregation of certain size characters especially kernel size, also the relation of kernel size to other spike characters.
