TESTS OF OSARLEY VARIETIES IN" AMERICA 175 
barley. At none of the stations, however, has Nepal produced high 
yields. At most of them it was among the lowest in yield. Many 
crosses have been made with other types of barley with the hope of 
producing high-yielding hooded varieties, but with few exceptions 
these have not proved worthy of note. Crosses with barleys of the 
Manchuria type have resulted in progeny in which the rachis is so 
brittle that large losses occur from shattering. 
HIMALAYA (C. I. NO. 620) 
Several importations of barleys of the Himalaya type have been 
tested on experimental farms. Others have most likely been gro^vn 
by farmers without having found their way to the stations. In all 
cases the type is quite similar. (PL III, fig. 2, C.) This blue naked 
6-rowed bearded barley is quite common in central Asia and occurs 
at the higher altitudes in northern India. It has given hi^lier yields 
than other naked sorts and is found in occasional fields tliroughout 
the barley-producing sections of the western mountain region of the 
United States. 
BLACK HULL-LESS (C. I. NO. 596) 
The Black Hull-less variety is widely distributed over central Asia. 
Its kernels when grown under semiarid conditions are brilliant purple 
at harvest time. As they dry, this purple darkens until the kernels 
are almost black in appearance. It is a 6-rowed bearded barley, 
like Himalaya, and has been tested and grown in the same general 
regions, but it has not proved to be the equal of that variety in yield. 
ACCESSION DATA OF CEREAL INVESTIGATION NUMBERS 
The barley varieties appearing in this bulletin have been acces- 
sioned under Cereal Investigations (C. I.) numbers. In a great 
many cases these varieties were received from foreign countries 
through the Office of Foreign Seed and Plant Introduction of the 
United States Department of Agriculture. In these cases the C. I. 
number is the one under which they were first grown by the Office of 
Cereal Investigations and distributed to the experiment stations. 
In many other cases the varieties were received from State experiment 
stations and accessioned. Many of the varieties have not been re- 
ceived by the department, especially those of Canadian stations. 
As they often were grown at several stations under different station 
numbers, it was necessary to accession these as well. 
In Table 94 the data occurring under the Cereal Investigations 
numbers are abridged in tabular form. The list of station numbers 
and synonyms must necessarily be incomplete. An attempt is 
made to indicate the character of the barley by stating that it be- 
longs in a certain group. Such grouping is necessarily approximate. 
For example, the Chevalier barleys merge into the Hanna types by 
way of the Bohemian group, which has some of the characters of 
each. There is some confusion as to whether certain varieties origi- 
nated in Austria or Germany. Conditions in these countries are so 
similar, however, that it is iimnaterial wliich is credited as the place 
of origin.
