a commercial way the Yellows Resistant work started in 1910 
by Professor L. R. Jones of the University of Wisconsin and 
continued by Dr. J. C. Walker of the same university. Each 
new development is approved by the University experts before 
it is offered to the trade. 
When Professor Jones was called in to investigate the disease, 
he very soon discovered the only remedy was to develop new 
strains resistant to the Yellows. Up to the present time, Professor 
Jones, Dr. Walker and co-workers have developed most of the 
varieties now in use. The production of Kraut varieties was 
financially supported by members of the National Kraut Packers 
_ Association. 
When these resistant strains were released by the University 
of Wisconsin, it was necessary that they be kept in a highly 
resistant form, and made available to the trade. The WISCON- 
SIN CABBAGE SEED COMPANY was then organized for 
this purpose. The work is directed by a plant pathologist es- 
pecially trained under Dr. Walker. The company maintains ex- 
tensive breeding grounds and an air-conditioned warehouse in 
the heart of the Yellows area of Racine County, Wisconsin. 
This catalogue presents the story to the highly important 
{Yellows Resistant work from inception to the present day. The 
company is devoting all its energy, resources and scientific ap- 
‘plications available to this one commodity in an endeavor to 
supply the trade with strains of uniform type and quality; to 
keep Resistance at the highest point possible; and to breed new 
strains. A new strain requires from 8 to 10 years to develop.
