TESTS OF SELECTIONS OF OATS. 
COMMERCIAL VARIETIES. 
In 1904 pure strains from commercial varieties were started from 
heads selected from the field plats grown that year in cooperation 
with the Funk Bros. Seed Co., at Shirley, 111. The series numbers of 
these pure-line selections are as follows : 
62. Sixty-Day. 
63. Burt. 
115. Red Rustproof. 
117. Early Champion (Alaska). 
118. Silvermine (Musselshell). 
119. Probsteier. 
120. Silvermine (Great Dakota). 
123. Welcome. 
124. Silvermine. 
125. Silvermine (Great American). 
131. Pringle Progress. 
132. Sixty-Day. 
137. Early Champion. 
138. Early Champion. 
142. Goldmine. 
165. Sixty-Day. 
5938. Sixty-Day. 
THE SYSTEM OF NUMBERING. 
As shown in the preceding paragraphs, each combination of varieties 
which was made was given a series number. Thus, all hybrids in 
which Sixty-Day, S. P. I. No. 5938, was the female parent and Clydes- 
dale, P. B. No. 8, was the male parent were of series 49. Each 
combination of individuals was designated by a letter, as a, b, c, etc. 
For instance, if crosses were made on three plants of Sixty-Day oats, 
using the same or different plants of Clydesdale as the male parents, 
these individual combinations were numbered 49a, 49b, and 49c. 
Each plant produced in the F x generation was numbered consecutively 
for each combination of individuals, as 49al, 49a2, 49a3, 49bl, etc. 
This number is always written as a unit. As individual plant selec- 
tions were made, these were given serial numbers, this number being 
separated from the hybrid plant number by a dash. As subsequent 
selections were made, these were also numbered serially. Thus, 
49a2-20-7 is pure-line selection No. 7 from pure-line selection No. 20 
from plant No. 2 of the hybrid combination No. 49a, Sixty-Day X 
Clydesdale. If a reselection was made after a lapse of one or more 
years without selection, this lapse is indicated by xx, as 49a2-20- 
xx-7. If a bulk selection was made, the selection number is written 
in Roman instead of in Arabic, as 51al-15-I. 
The selections from commercial varieties were numbered in the 
same manner as those from the hybrids. Each stock was given a 
series number, but the numbers of pure-line selections from commer- 
cial varieties do not contain a letter followed by a numeral, as is the 
case in all hybrid numbers. Each individual selection bears the 
series number followed by a serial number within the series and 
separated from it by a dash, as 125-17. Bulk selections, as in the 
hybrids, are indicated by Roman numerals. Thus, 62-II-18-1 is 
the progeny of plant No. 1, selected from the progeny of plant No. 18, 
which in turn was selected from Bulk Selection II from the original
