Table II. — Coefficients of Ilercdiiy of Single Lines. 

 Vine Lerujlh. 



A study of this table shows it to be in harmony with the first 

 three conclusions drawn from Table I. It indicates further that 

 the true coefficient of heredity within these single lines of Ex- 

 celsior i^eas is about +.06 for vine length and practically zero 

 for pods per vine. 



There is generally a positive correlation between seed weight 

 and the size of the plant produced. The question which now 

 arises is whether this is sufficient to account for the small plus 

 correlation in vine length shown in Table II. AVe have a few 

 figures bearing on this point, but not enough to determine posi- 

 tively whether this is the case or not. The seed weights avail-
