Figure 55 shows a facsimile of the blank on which data re- 

 grading the straw, leaves, heads, grain, yield, disease resistance, 

 etc., are recorded.

Pw- 55- Facsimile of Oat Breeding record used in the oaf variety tests 



Finally Figure 56 shows the plot index. Plot numbers are 

 never duplicated so that by the use of this index it is possible 

 to trace back the pedigree of any strain. This same blank is 

 used for all plant breeding work. Hence, in the third column, 

 under the heading "Plant," the kind of crop, whether oats, corn, 

 beans, etc., is indicated. Under the heading "Seed used" there 

 is given both the variety and the source of the seed. 



In 1910 the variety tests were under the supervision of one of 

 the writers (F. M. Surface). In 191 1 the tests were in charge 

 of Dr. E. P. Humbert, at that time Associate Biologist in the 

 Station. In 1912 and 1913 the tests were again under the super- 

 vision of one of the writers (C. W. Barber). To Dr. Raymond 

 Pearl is due the credit for the continuity of these tests during 

 the several years and for many suggestions during the course of 

 the work.
