"Every individual corn plant is possessed of a distinct individ- 

 uality which corresponds to the individuality of animals. 



"For guidance in conducting the breeding plot, certain recom- 

 mendations founded upon these well-established principles are 

 here given as being advisable to follow." 



Ear Row Breeding Plot. 



"Seed ears of desired type and quality should be tested by 

 planting each in a separate row in the plot in order to prove its 

 productivity as well as to test the transmission of other charac- 

 ters." 



Size of Breeding Plot. 



"The larger the number of ears included in this plot, the better 

 it will be. This is on account of two reasons, first, for the sake 

 of affording as great a range of selection as possible ; and second, 

 to avoid future detrimental effects of in-breeding resulting from 

 the establishment of too close relationships. 



" A system of 90 rows is recommendable as explained in Bulletin 

 No. 100 of the Illinois Agricultural Experiment Station. As 

 regards length of rows it may be said that in general the longer 

 the rows, the better the test. Rows at least 100 hills long are 

 recommended." 



Registration. 



"In order to keep the pedigree, each seed ear should be given 

 a register number to correspond to the row in which it is planted. 

 For the sake of obtaining all possible information regarding the 

 connection between type of ear and productivity in each of our 

 varieties, it is well to record at the same time some description of 

 each seed ear. This may include such data as size, weight, 

 number of kernels, notes concerning type of kernel and of ear, 

 etc." 



Performance Record. 



"At harvest time the performance record of each row should 

 be determined by weighing the total amount of ear corn produced. 

 This performance record may well include other desirable points
