This photograph, showing a section of the Clemson Fiber Laboratories, was 
furnished through the courtesy of Mr. John M. Cook, Seni-r Fiber Technologist 
in Charge (shown in photograph above, standing). We are reproducing it here 
to illustrate some of the tests to which our breeding material is subjected in 
our program of breeding cotton for improved fiber and spinning quality. 

This picture shows testing cotton for length with use of fibrograph, also 
testing for strength by Pressley Tester, and using Suter-Webb sorters in making 
arrays from which length and length uniformity will be determined. These 
sorted fibers are also used in determining the fineness and maturity. 

Announcing an Important Change in 
Our Breeding Program 
For this coming season we are offering only one variety 
of cotton in the medium length staple class—Coker 100 
Wilt, and one long staple variety—Coker-Wilds. We have 
discontinued our Coker 200 and Coker 100 non-wilt vari- 
eties and our Coker’s 4-in-1 wilt resistant cotton. 
ONE GENERAL PURPOSE VARIETY 
At the urgent request of the Cotton Division of the 
Bureau of Plant Industry, USDA, and of others, we have for 
the past several years been working toward reducing the 
number of our strains and varieties of cotton in order to 
aid in the program of standardized cotton production. How- 
ever, it was not until we had bred our Coker 100 Wilt Re- 
sistant up to its present standard of performance and wide 
adaptability for both wilt and non-wilt soil that we felt 
that we could safely eliminate the varieties mentioned 
above. 
We are convinced that it will be of greater advantage to 
our customers and distributors for us to offer one, supe- 
rior, general purpose cotton—Coker 100 Wilt, adapted for 
planting anywhere that cotton is grown in the Southern 
Cotton Belt, rather than to offer several good varieties 
suited for special purposes, or for certain soil types and 
localities. 
STRAIN NUMBERS ELIMINATED 
We have also decided on a change in our established 
method of identifying our varieties of cotton seed, oats, 
wheat, corn, tobacco, etc., of which we believe our customers 
will approve. 
Hereafter we will eliminate strain numbers on our vari- 
eties of seed, and instead will identify these varieties by 
the date or year the seed were produced. As an example: 
our new Coker 100 Wilt cotton for 1947 planting is being 
labeled Coker 100 Wilt—1946 Breeder Foundation Stock, 
and our new Coker-Wilds as Coker-Wilds—1946 Breeder 
Foundation Stock. 
This change is being made in order to avoid confusion 
between different strain numbers of the same variety, and 
so that our customers will know the year that these strains 
and varieties were produced for sale by us. We will of 
course continue to improve our Breeder Foundation Stocks 
each year with our newest and best lines from our wealth 
of breeding material, but we will maintain the standard 
type and recognized characteristics of the variety. 
This reduction in the number of our cotton varieties has 
enabled us to concentrate a great deal more breeding and 
attention on the ones we are offering, and should mean 
that our breeding program with them will show even more 
rapid progress and greater improvement in the future. 
1946 SEED CROP OF HIGH GERMINATION 
The weather this fall has been almost ideal for gathering 
our crop and, as this catalog goes to press (mid-October), 
indications are that we will have a seed crop of high 
germination and excellent quality. The demand for our 
pedigreed foundation seed is heavy, and we hope that our 
customers will not delay too long in booking the seed they 
will need for the 1947 planting season.
