RAMOSE INFLORESCENCE IN MAIZE.

ber of branches, the length of the branching space, nor the central 

 spike index would measure properly such behavior, as all would ap- 

 proximate closely the dimensions of a normal tassel. 



Table V. — Distribution of plants of the second, third, and fourth generations 

 of the Ramoisa-Gordo maize hybrid Mhl58 for the number of branches in 

 the ear. 



IThe distribution in the second generation is for ramose plants only. The position of 

 the parental ear is indicated either I)y italic figures or by a plus mai-k. R indicates 

 ears classed as ramose, since the number of branches exceeded 50.] 





Progeny distribution differentiated by parents (number of plants).

The F4 progenies demonstrate the possibility of isolating true- 

 breeding intermediate forms, though the progenies differed among 

 themselves in the degree of branching, viewed either from the stand- 

 point of the tassel or from that of the ear. Nine of the progenies 

 produced some plants with typical ramose ears, one progeny having 

 as many as 12 plants Avith ramose ears in a population of 20.
