Improvement by Selection and Breeding.^—The ear row method isthe most satisfactory way of improving corn along any line. This methodis based on the principle that like begets like, but fortunately this prin-ciple is not rigid. It is the variation in the progeny of any parent plant thatenables us, through selection, to improve the variety, and it is the tendencyfor like to produce a larger percentage of progeny, differing but slightlyfrom the parent that enables us to make progress in plant improvement. Corn improvement by selection is easy, because the plant is largeand its characteristics plainly visible; because the variations are suffi-ciently marked and frequent to enable man to select individuals with.

Corn breeding is somewhat difficult because of the natural cross-fertilization and the impracticability of keeping the breed pure, and alsobecause close and self-fertilization are difficulties that must be guardedagainst. None but the choicest ears selected for desirable qualities ofboth ear and plant should be used in the breeding plat, and any ears thatdo not show a high standard in the germination test should be rejected. The selected ears should next be tested for yield and ears should be numbered and a portion of ea
