GENEDICSIAND PLAN T BREEDING 
Project 1: Inheritance in plants 
Scope: : 
1. The determination of the manner of inheritance of char- 
acters in certain plants, especially in the genus Pisum. 
2. The determination of the interrelations of the hereditary 
character-determining influences or elements (factors or genes). 
3. The influence of environmental differences on the expression 
of these hereditary units. 
4. The relation between the hereditary units or factors and the 
chromosomes. 
5. The frequency of origin and the distribution of certain char- 
acteristics. 
In the prosecution of these studies, it is planned to employ the 
best available material. So far, peas have been largely used, be- 
cause they have many peculiar advantages over other plants. To 
some extent, castor beans, maize, and Nicotiana have been em- 
ployed. 
Status: 
Studies on the inheritance of fasciation and other striking ab- 
normalities in Nicotiana, Chenopodium, Celosia, Erigeron, maize, 
and other plants have been carried out and reported on in pub- 
lished form. Some types of fasciation (ribbon-like stems, in- 
crease in tissue, and often distorted flowers) have been found to 
be primarily the result of inheritance. Other types are mainly 
due to special kinds of environment.
