Numerous investigations have been conducted on the relation between seed ear characters and-productiveness in corn. Most of these have been reviewed in some detail elsewhere (2, 4)? and need no mention here, except to state that, in general, there seemed to be a small but consistent tendency for those ears which are heavier and longer and which have fewer rows, smoother indentation, and lower shelling percentages to produce the larger yields? The suggestion was made (3) that part of this apparent relation between yield and ear characters might be a reflection of one between yield and kernel characters, and, if so, kernel characters might have some b~aring on the kind of seed ears desirable for planting. A fairly extensive ear-row planting of Pride of Saline corn was made for other purposes at the Kansas Agricultural Experiment Station. Accordingly, it seemed worth while to measure some of the kernel characters, as well as ear characters, and to determine the relation to yield. These studies are herein reported.
