Results of Cotton Variety Tests in Alabama for the Period
1925.1929, Inclusive.
During the cotton marketing season of 1930, a greatly increased interest
in quality of cotton has been developed by farmers due to the dockage assessed
against cotton with a staple below 7/8 inch in length. 
This stimulated interest
has caused numerous inquiries for information relating to desirable varieties as
shown y tests conducted in the state by the Alabama Experiment Station. 
Since
a full report on varieties tested in 1930 will not be available before January,
it has been decided to present a complete review 
of the tests conducted from
1925 through 1929 These results are summarized in table form on the second page
of this report.
In columns 1 and 2 of the table will be found average yields of lint
cotton and average lengths of staple of the varieties tested 
in North Alabama.
Especial note should be made that varieties named near the bottom of the table
have not been tested over the five-year period, but are 
included because of the
fact that they are popular varieties, but have a very 
poor quality. High-yielding
varieties in North Alabana that have consistently produced a staple of 28/32, or
longer,.are Cook 1627, D. P. L. 4-8, Delfos, and Trice. 
The last three varieties
,named are not as easily picked as Cook 1627, but have a slightly better staple
than the Cook strain.
Results for Central Alabama are shown in columns 3 and in 
the table.
1igh.yielding varieties in this group are Cook 1627, D. P. L. 4-*8, Dixie-Triumph,
PiedmontCleveland, Wannamker..leveland, Cook 588, and Cook 307?(Rhyne).'Of
these high..yielding varieties, only Cook 1627, D. 
P. L. 4-8 and Dixie-Triumph
have consistently produced a staple 28/32 of an 
inch or longer.
In the last two columns of the table are reported the results for
wilt-resistant varieties tested in South Alabama. The highyielding 
varieties in
this group are Dixie-Triurmph, Cook 307 (Rhyne), and Toole (Council), 
Each of
these varieties has produced a staple below~ 7/8 of an inch one or more 
times
during the last five years. D. P. L. 6 in six tests in Central Alabama has 
proved
to be quite wilt resistant and has produced nearly as much 
lint cotton as Cook 307.
The staple is slightly longer thaji one inch. This strain of D. P. L. Cotton is
not easily picked.
The results are set forth in detail in the table, and it is hoped that
anyone interested in cotton varieties will carefully study the table. To interpret
the staple length, one should remember that 28/32 is the same 
as 7/8 of an inch,
