Genetics and Plant Breeding 



The Genetic Analysis of Garden and Field Peas 



By Orland E. White 



Investigation^ on garden and held peas (Pisnni) have been con- 

 tinued in 1927, along lines similar to those mentioned in previous 

 reports. The work on the inheritance of cotyledon shape and 

 color and their genetic relationships to other characters will be 

 ready for publication in 1928. Data have been secured on the 

 inheritance of a large number of other characters and their re- 

 lationships to each other, particularly in regard to flowering Line, 

 flower color, and height. < >rher investigations involved studies 

 on the inheritance of purple, yellow, and green pod colors and 

 their genetic relations with purple seed-coat color. 



Studies of the Variation of the Boston Fern (Ncphrolepis) 



By Ralph C. Benedict 



The collections of Boston Fern types in the public houses and 

 111 the experimental house have been continued along the lines of 

 previous years: namely, the maintenance of the most important 

 bud variations, and also of the sporeling types, together with a 

 if experimental testing of various forms of special
