BULLETIN 1155, U. S. DEPARTMENT OF AGRICULTURE. 
No. 2294 also slightly outyielded Shinriki, averaging 2.85 pounds to 
the row. Other high-yielding strains were C. I. Nos. 1465, 2293 
(Fukuyama), 2295 (fakenari)", 2300 (Shinriki), 2303 (Miyako), 
2332 (Tse-Nishiki), 2337, 2338 (Takenari), 2348 (Samba), and 2359. 
The average yields from the rod rows for the 5-year period show 
Omachi (C. I. No. 2316), to be slightly in the lead, with 3.04 pounds. 
A strain of Wataribune (C. I. No. 1561), is second, with 2.93 pounds. 
Shinriki (C. I. No. 2300), averaged 2.87 pounds for this period, while 
11 other varieties averaged 2.50 pounds or better. Honduras, Caro- 
lina Gold, and Carolina White, standard long-grain rices in the 
Southern States, averaged less than 2 pounds to the row. 
Table 27 shows the annual and average yields in pounds per rod 
row for the 133 varieties and selections grown in bulk rows in the 
nursery. The bulk rows were seeded at approximately the same 
rate as that used on commercial fields. These rows, except new 
importations, are pure-line varieties or selections. The bulk rows 
have given better yields as a rule than the head rows, due in part to 
thicker seeding and better stands. Yields of the check rows of 
Wataribune rice are also given. 
Table 27. — Annual and average yields of 133 varieties and selections of rice grown in 
bulk rod rows in the nursery experiments at the Biggs Rice Field Station, Biggs, Calif, 
during periods of varying length in the six years from 1916 to 1921, inclusive. 
[The superior index figures represent the number of rod rows included where more than one was grown.]
