Kiichi Miyake and Yoshitaka Imai :— The Genetic studies in 

 Barley. I. 



Studying the genetic behavior of Barley, the authors detected 16 

 pairs of allelomorphs affecting plant-habit, ear, glume, awn, grain 

 etc. The allelomorphs responsible to the development of the awn of 

 the lateral rows of the ear, consist probably of three factors, i. e., 

 they form multiple allelomorphs. Linkages observed were not few, 

 and the authors found two large linkage groups of factors. One of 

 them consists of four or probably five factors and the other of five 

 factors.
