Notes 



Each figure was obtain- 

 ed by taking 10 shoots, 

 measuring the widest 

 leaf and taking an 

 average of the ten. 



The average of all the 

 seedlings in Chittan, 

 for instance, is the 

 grand average of the 

 averages above men- 

 tioned in all the 5J9 

 seedlings 



The " Extreme Cases ' 

 are the lowest and 

 2-0 M highest averages ob- 

 tained in these 509 

 seedlings. 

 Two sets of observa- 

 tions were made for 

 the parents, but in 

 neither case were 

 these well grown. The 

 figures for the parents 

 are thus only approxi 

 mations.
