One family (from Ee parent), LV-486-35, shows a ratio of long- 

 podded mean to short-podded mean of 1.5. 



In the families of IvV-92, the parents ranged from 82 to 97. The 

 progenies did not sensibly differ. Judging by these, LV-92 was homo- 

 zygous for minor factors. The same applies to the families of VL-297. 



On the other hand, the families of VL-515 showed evidence of the 

 segregation of a minor factor; a segregation also marked in the field. 



No indubitable evidence of segregation can be seen in the other 

 fourth-generation families. 



In Table XI the pod lengths of the third-generation parents are com- 

 pared with those of their long-podded progenies. The average of the 

 whole shows an insignificant excess of pod length in the progenies.
