while those of the raw grains are closer to the pollen 

 parent. With one exception, in all of the qualitative 

 reactions of all four hybrids the relationship is closer 

 to the seed parent. Excess of qualitative development 

 was noted once, deficit once, and individuality not at all. 

 The quantitative reactions are frequently intermediate, 

 sometimes the same as or higher or lower than both 

 parents; usually very much closer to the seed parent 

 and far separated from the pollen parent, and rarely 

 the same as or closer to the pollen parent. 



RiCHABDiA. (Table C 12.) 



In form, polariscopic figure, selenite reaction, and 

 iodine reaction the hybrid inclines to the pollen parent ; 



in lamellae it is equally related to both parents; and in 

 all other designations closer to the seed parent. Deficit 

 of development was noted twice, excess of development 

 once, and individuality not at all. 



The quantitative reactions are quite variable in their 

 parental relationships, and vsdthout other than casual 

 correspondence in their bearings with the qualitative 

 reactions. 



MusA. (Table C13.) 



With the exception of the number of the lamellae, 

 the designations of this hybrid are toward the pollen 

 parent. The quantitative reactions are in all seven 

 designations toward the pollen parent.
