- Observations on the development of the seminal roots in corn show that there is a great variation in number of secondary seminal roots produced in different seedlings; that individual ears possess characteristic tendencies in this respect; and that varietal differences are also noticeable. Data are presented showing a positive correlation between high seminal root production and yield of crop. There is also some evidence that high seminal root production tends to enhance vigor of early growth. Based upon these findings it is suggested that the observation of seminal root production in connection with the germination test may furnish an additional item to the list of aids in selecting seed ears of higher productiveness.
