hy txptiinuiit slalions in boll weevil territory, seems 

 to show that some of the medium early varieties often 

 produce a greater money value per acre than the ex- 

 tremely early varieties like King or Simpkins. Cer- 

 tainly where boll weevils are absent or few in numbers, 

 as at Auburn in 1915, certain medium early varieties 

 have surpassed in yield the extremely early varieties. 



Briki Description of Wilt-Resistant Varieties of 



Cotton Used in Experiments. 



DILLON. 



In 1!»()() some will-resistant plants were selected by a rep- 

 resentative of the U. S. Department of Agriculture from a 

 badly infected field of .Tackson Limbless cotton growing near 

 Dillon, South Carolina. This selection was later named Dillon 

 to distinguish it from Jackson Limbless, its parent. Small 

 quantities of seed of this new variety were widely disti-ibuted 

 over the wilt-infected sections of the Cotton Belt, but this 

 variety did not prove very satisfactory because of its cluster 

 habit, lateness in maturing and difficulty in picking. It is 

 the most resistant variety to wilt and nematodes thus far 

 tested by the Alabama Experiment Station. 



The Dillon plant grows tall on fertile soil and usually has 

 one, two or three large base limbs. Its fruiting limbs are 

 short and its bolls grow in clusters. The bolls are small, 

 slender, somewhat pointed and difficult to pick. Tlie seed 

 are small and fuzzy. Its fiber is about 7-8 inch long; its per- 

 centage of lint is about 37. 



MODELLA. 



This variety originated in Georgia some years ago. It was 

 selected from Excelsior by Mr. A. C. Lewis of the Georgia 

 State Board of Entomology and resembles the old Peterkin va- 

 riety. The plants are medium size and have many small 

 straight limbs with three or four base limbs. The bolls are 

 medium size and about 80 to 85 of them make a pound of 

 seed cotton. The seed arc small and many of them arc smooth 

 and black. The percent of lint is about 35; its fiber is from 

 3-4 to 7-8 inch long. This variety is late and lacks storm 

 resistance. 



COOK. 

 Cook variety, which was used as a check in most variety 

 tests, came from the breeding experiment at the Alabama Ex- 

 periment Station, and represents one of the most productive 

 strains of this variety. The j)lants are intermediate in type and 

 have two or three base limbs with many long fruiting limbs. 

 The bolls are medium large, open wide and are easily picked. 

 This variety is medium early, tnit is lacking in storm-proof 

 ([ualities. The seed are small and very fuzzy; the fiber is 

 short and strong. It turns out at the gin 12 to 43 percent of 

 lint. This variety is very susceptible to will and nematodes, 

 and for this reason it was used as a check in the variety tests.
