TILLERING POWER OF STONER (MIRACLE) WHEAT. 
Tests to determine the tillering power of Stoner (Miracle) wheat 
were made at Arlington Farm by sowing, in both 1912 and 1913, 
individual kernels of this variety and of three standard varieties, 
each kernel being given plenty of room for maximum development. 
These kernels were sown 6 inches apart in rows 1 foot apart and 5 
feet long, in uniform soil, the order of sowing being that given in 
Table IX. All varieties were grown under identical conditions on 
small adjacent plats of land.

Average number of culms per 
plant 
12.2 
Table IX shows that in 1913 the 41 plants of Stoner wheat pro- 
duced an average of 8.7 culms to the plant. This is the smallest 
number produced by the plants of any of the varieties used, Martin 
Amber producing 9 culms, Dietz 10.3, and Fultz 10.5. 
The results for 1914 are similar to those of the previous year in 
this respect, that the plants of Stoner wheat again produced the 
smallest average number of culms, there being in this year 9.6 to the 
plant of this variety. Fultz produced 10.1, Dietz 10.4, and Martin 
Amber 12.2. The tests for these two years indicate, then, that 
Stoner is the poorest of these four wheats in tillering power. These 
results also show that in neither year was there a larger number 
of culms than 18 produced by any plant of the Stoner wheat, while 
there is a total of ten plants of the other varieties in the two years 
which produced more than 18 culms each.
