PLATE 51 
Seeds with combed-out fiber of Pima cotton grown in 1919, showing range in abund¬ 
ance 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 highest 
and the lowest lint index, respectively. The comparison shows a greater variation 
in abundance and a lower minimum abundance in the parent progeny than in the 
present commercial stock.
