That no visible characters of the corn ear are indicative of high yielding power has been demonstrated many times by breed- ers and this fact is clearly summarized by Hartley as follows: "A careful tabulation of yields as compared with other ear characters covering six years' work with four varie- ties, embracing in all more than 1000 ear-to-row tests of production, indicates that no visible characters of appar-.
