plant breeding work of the Station. For those plants which 

 are later multiplied in plots, the plant selection number be- 

 comes the "Line Number." Thus when we speak in the latter 

 part of this paper of Line No. 355, it refers us at once to selec- 

 tion number 355 and from this the entire pedigree of the line 

 can be traced. So long as no new germ plasm is added by 

 crossing, the line number remains the same. 



Notes were taken at the time of the original selection of each 

 plant. These notes were recorded on 5" x 8" loose leaf sheets 

 similar to that shown in facsimile in Figure 15. These sheets,

This sheet provides space for data relating to the pedigree of 

 the plant and also such characters of the plant as height, num- 

 ber of culms, weight of grain and straw and certain characters 

 of the head and grain. At the time of the field selection, the
