The inheritance of "beardedness is an unBettled 

 question and offers a very good opportunity for an accurate 

 and detailed statistical study from a Mendelian standpoint. 



The color of awns iB e chf racter which is probably 

 intermediate in F]_. Thepe is, however, scarcely sufficient 

 evidence to support this statement. 



The record of the inheritance of lexness or denseness 

 in the ears seems much more conclusive. F^ hee practically 

 the same head, so far as laxness is concenied, as does the 

 parent with the laxer head. Biff en reports that loose 

 heads are dominant to compact heads. 



W. H. Parke r-^^ in a rather extensive report of "Lax 

 and Dense-eared Wheat" finds the problem of inheritance of 

 denseness and laxness a very complex and entirely unsettled 

 one. His results are conflicting and definite conclusions 

 cannot be drawn from them. 



Prof. Spillman*-^-^ reports 14 crosses of dense and 

 lax wheats with the result of 1 lax; 2 intermediate; 1 

 dense. His actual percentages were 27.2; 47.2; 25.6. 

 The different varieties gave very different results but the 

 above percentages are the average of all his oxosses. 



Uilsson-Ehle-^-"^ ■'■■'■ finds a 1:2:1 ratio in Fg with 

 dense and lax-eared wheats. 



Sufficient evidence is not given in F of the crosses 

 reported in this paper to indicate accurately how the color 

 of glume is inherited.
