Figure 7. — Diagram illustrating structure of High-protein kernel. 



■ 



Following the fact that about four-fifths of all the oil in the 

 kernel resides within the germ, the selection for high-oil has re- 

 sulted in a kernel having a relatively large proportion of germ, 

 while the low-oil selection has produced a kernel whose germ occu- 

 pies a relatively small proportion of its bulk. These relations are 

 brought in figure 10, which represents kernels from high-oil and 

 low-oil ears, on the left from a high-oil ear testing 6.08 per cent; 

 on the right from a low-oil ear containing but 3.64 per cent of oil.
