COTTON VARIETIES 



47 



are rather tall and sl'ender with few or no priniary limbs. 

 The bolls are small to medium, in size with 3 to 5 locules, 

 and the lint is borne in rather >closely miatted locks. 



It is claimed that a few varieties of this group have been 

 produced by cross- 

 ing upland and 

 Sea Island cotton. 

 However, in most 

 cases the varieties 

 have been pro- 

 duced by straight 

 selection. Several 

 varieties, of which 

 Griffin and Colum- 

 bia are examples, 

 have been devel- 

 oped from the big- 

 boll group. 



The upland 

 Jong-staple varie- 

 ties are best 

 adapted to fertile 

 river bottom soils. 

 They are grown 

 rather extensively 

 along the Red 

 River in Arkansas 

 and Texas, and 

 along the Mississippi in Mississippi and Louisiana. 

 The yield is often lower than that obtained from 

 the upland varieties but the greater value of the 

 lint usually more than offsets the difference in 

 yield. -Examples of the long-staple group are Grifiin,
