Two to four different ears may be used as dams, an ear to a row, detasseling, of course, every row, except the sire rows. In this way three or four distinct crosses may be secured; crosses in which both parents are known, and their performance records as well. As this system continues, the performance records, not only of sire and dam, but of grandsire and grand-dam—and on indefi- nitely, are a matter of record. CHART THEORY AND PRACTICE. I come now to my third question— How much of the superiority, which we discover by means of the ear-row test and attempt to perpetuate, can we hope to trans- mit to subsequent generations ? In answer to this question, I want to call your attention to the average yields of a duplicate ear-row test of 30 ears, conducted the past season at the Ohio Station (Chart IV). Of these 30 ears 18 were /new selections from the field, and consequently of unknown pedigree, and without performance rec- ords ; 9 were pedigreed crosses from the breeding plot of the year previous, sire and dam, and the performance records of both known, while 3 were inbred pedigreed ears selected from the sire rows. The 9 pedigreed crosses are Nos. 33, 34, 38, 41, 42, 48, 51, 55.
