PARENT FORMS AND FIRST GENERATION HYBRIDS WITH THE DWARF BARLEY 



I'kuke 15. The two parent forms on the left are Nepal and Manchuria. The type of heads 

 obtained by crossing these two species with the dwarf form are shown on the right. No "dwarf" 

 characteristics are found in the first generation, but in the second generation segregation of normal 

 and dwarf forms occurred in a ratio of approximately three to one, indicating that the dwarf 

 character is a Mendelian recessive.
