Abstract
IT is well known among maize-growers that the number of rows of grain on an ear of maize varies from 8 to 24, or even more, according to the breed; also that in the same breed the number may vary within certain limits, e.g. 8, 10, or 12 in some breeds, 12, 14, 16, or 18 in others and 18, 20, 22, or 24 in yet others. In some breeds the range of variation is even greater than I have indicated, while in others it seems to be more closely limited. In some breeds an ear carrying more than 8 rows is considered untrue to type, but I am not aware that any South African grower has yet succeeded in fixing the number of rows in any breed to such a degree that no variation occurs in that respect.
