210 FIELD CROPS FOR THE COTTON-BELT 



If the varieties differ 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 

 by the 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."
