Mendelian inheritance in wheat and barley crosses, with probable error 

 studies on class frequencies, A Ki nt and B. BoTACX (ObiOftMlO stn. Bui.

ini1 in which crosses were made between different varieties of wheat, wheat 

 and emmer, and between varieties Of barley In n study of Mendelian inheri- 



tance of characters. The behavior of the Fi progeny and the s egr egations in 



the I' -'''ration are described, and observations made upon certain progenies 



continued Into the '" generation recorded. Considerable data are presented 

 which have been subjected bo a theoretical analysis showing the probable error 



Of Mendelian .lass frequencies and the Conformity Of the material thereto. 



Stating that if the chars ganism are the developmental results 



of certain factors inherited according to the Mendelian law, their occurrei 

 in numerous samples Bhould be such as to conform to the binomial frequency
