SOME NEW VARIETIES OF RICE. 
15 
This variety matures in approximately 143 days and has produced 
an average acre yield of 2,500 pounds of paddy and 1,734 pounds of 
straw. It is not grown on a large acreage in the United States, 
mainly because its culms are too short to be cut with a binder with- 
out the loss of some grain, even when the plants produce a normal 
yield. This loss, of course, does not occur in Japan, where the variety 
is extensively grown, because the crop is cut with hand hooks. The 
Shinriki and Wataribune varieties are usually quoted as " Japan 
rice " in the southern rice markets of the United States. 
COMPARISON OF VARIETIES. 
The stems and foliage of the varieties described, except Delitus, 
Evangeline, Vintula, and Honduras, retain their green color after 
the grain ripens. Usually the entire plant of these four varieties 
matures rapidly, the leaves turning yellow as the grain ripens. 
Uniformity in the size of the seed is strikingly characteristic of 
the Fortuna, Acadia, Delitus, Tokalon, Wataribune, and Shinriki 
varieties. The seeds on the lower part of the panicles of Evangeline 
and Honduras often vary in size. When grown on poor soil, Evan- 
geline, Honduras, and Blue Eose often produce stunted panicles, 
bearing imperfect seeds. The dimensions of the seeds of all varieties 
are shown in Table 1. 
None of these varieties shows complete resistance to the fungous 
disease (rotten-neck) caused by Piricularia oryzae Br. and Cav. 
Honduras is very susceptible, and all of them may be seriously af- 
fected by this disease if they are left uncut too long after maturity. 
The conditions which produce the straighthead disease have no ef- 
fect upon Fortuna and Vintula, as so far observed.
