o Yield reduced about 75 per cent by birds. 
Most of the varieties and strains which have been grown in bulk 
rod rows are pure-line selections. Every eleventh row in this nursery 
was sown to Wataribune rice (C. I. No. 1561) as a check. Of the 
few selections grown for six years, none outyielded the check, two 
rows of which averaged 3.65 and 3.85 pounds! The highest yielding 
selection was No. 216, with 3.61 pounds. 
A large number of varieties and pure lines were grown during the 
five years from 1917 to 1921. Only two of these. Selection No. 115, 
with a yield of 3.90 pounds, and C. I. No. 2030 i Omachi) outyielded 
the nearest check rows of Wataribune.
