Department of Agronomy
Beginning with 1911, and continuing throughout the even cropping seasons following, South Dakota Experiment Station, Agronomy Department has conducted two systems If corn breeding by ear-to-row selection. During the seasons wherein these breeding-plots have been conducted, the actual carrying out of field work and of seed selection has been participated in by all members of Agronomy Department Crops Division. These systems of corn breeding were installed partly with the idea that they might produce comparative results in the form of ear-row-yields which would be helpful in defining a practical corn breeding system, which could be recommended to farmers as superior to other systems. One of the corn breeding-plots here reviewed is patterned after the plan devised by Hopkins and described in Illinois Experiment Station Bulletin No. 100. Through the seasons of 1912 and 1918 inclusive, this ear-to-row heeding plot has been conducted at South Dakota Experiment Station1Brookings field. According to this system, it should be remembered that in whatever year of the breeding plot, the separate rows are planted with seed from separate mother ears. Also this system calls for detasseling all stalks of the even-numbered rows in all quarters of the breeding plot every year, and seed ears for succeeding years are always selected from the six highest-yielding, even-numbered rows of each of the four quarters of the plot. This latter rule has been adhered to in connection with the breeding plot under discussion except in cases where rows yielding the highest weight of ear corn were found to be very inferior in other respects.
