STUDIES IN INDIAN SUGARCANE SEEDLINGS 



LEAF MODULE AND SUCROSE. 



Correlation 3. 



The leaf module, as explained in the section on Variation in Morphological 

 Characters, is the average extreme leaf length divided by the average extreme 

 leaf width, a factor noted in a previous paper^ as of some value in distinguish- 

 ing North Indian canes. In the general collection series there is a distinct posi- 

 tive correlation between leaf module and sucrose. The series is however marred 

 bv the KaruH seedlings, where the curve is irregular, owing to the high sucrose 

 content in two classes early in the list, and there is thus only a tendency 

 towards a positive correlation. The crosses again agree in differing fiom the 

 rest, which is not surprising, in that the present correlation is a combination 

 of the two previous ones. Nuanal also shows a distinctly negative tendency.
