During the five-year period from 1918 to 1922, inclusive, and the 
six-year period from 1918 to 1923, inclusive, the short-grain mid -sea- 
son varieties Bujen-ho (C. I. No. 2322) and the unnamed C. I. No. 
2337 both produced higher average yields per row than the nearest 
checks. Other comparatively high-yielding mid-season short-grain 
varieties during the six-year period were Sekitori (C. I. No. 2342), 
(C. I. No. 2343), and Tama-Nishiki (C. I. No. 2323). 
Of the late short-grain varieties grown during the six-year period 
from 1918 to 1923, inclusive, the four leading varieties were C. I. 
No. 1925, C. I. No. 2359, Usa-Nishiki (C. I. No. 2339), and Yamato- 
Nishiki (C. I. No. 2355). Other high-yielding varieties include C. I. 
No. 2350, Wataribune (C. I. No. 1561), and Wase-Shinriki (C. I. 
No. 2346). 
Of the early-maturing and late-maturing medium-grain rices grown 
during the five-year period from 1918 to 1922, inclusive, none equaled 
the nearest check in yield. Sam Sai (C. I. No. 1331), a late variety, 
and Nun Key, an early variety, were the highest yielding varieties of 
this general type. 
Jippon Tsu (C. I. No. 1338) was the only early long-grain variety 
grown during the five-year period from 1918 to 1922, and it yielded 
considerably less than the nearest check. During this period the un- 
named C. I. No. 2155, a late-maturing long-grain variety, exceeded 
the average yields of the nearest check. Ail other varieties of this 
group, except C. I. No. 1577, were distinctly inferior in yield.
