The seed colour has been investigated by Fruwirrn (1915) and 
Kasanus (1912). Fruwirtru has obtained a type with dark, self-colou- 
red seeds. He has studied its inheritance, and he has arrived at very 
peculiar results. I have had no type of this kind in my material. _ 
Kasanus has classified different types of seed colour, but no 
study of their inheritance has been made by him. I am much in- 
debted to Kasanus for receiving material of the different types of — 
seed and flower colours. 
THE MATERIAL. 
The following pure bred lines have been used as starting material. 
1. Flower colour: Blue Seed colour: Earth-brown, marbled 
and white punctured.

In the course of the experiments the following new types have 
been obtained as recombination products:
