The types with compact spikes in general are greater seed producers, and hence of more 



commercial value. (Fig. 4.)

In selection work, such as the isola- 

 tion of high oil ])rodiicing types, it 



seems best and most ])ractic;il to insure 

 com])lete isolation b\- using paper bags 

 as mentioned above. In making crosses, 

 the male flowers may be easily removed 

 without harming the spike and the re- 

 maining female flowers. Male flowers 

 usually mature and shed their jiollen 

 in earl\- morning. The pollen remains 

 \ial)le for at k'a>l a week, when kei)t
