PLATE 50 
Seeds with combed-out fiber of Pima cotton grown in 1919, showing range in length 
of fiber: A and B from the plants in the progeny of the parent of the variety and C and 
D from the plants of the commercial stock (strain 5-3) which had the longest and the 
shortest fiber, respectively. The comparison shows a greater variation in length and a 
lower minimum length in the immediate progeny of the parent plant than in the 
present commercial stock.
