If the varietifes dififer in date of tasseling it is recommended 

 that the variety which tassels first be used for the female 

 parent, as the silks are receptive, as a rule, for a longer time 

 than during the shedding of the pollen. If the varieties 

 do not differ in the date of maturity, seed may be obtained 

 by1;he following plan which will necessitate the using of 

 only one plat. To illustrate by the use of the diagram 

 for Plat 1. Reserve some seed of C; detassel all of C this 

 year. On the following year use the reserved seed of C 

 and the open pollinated seed of D for the seed-plot, using 

 D this- year for the female parent and reserving enough of 

 D for the following year."
