IMPROVING THE QUALITY OF WHEAT, 



TABLE 35. Summary of relation of size of head to yield, height, and tillering of plant. 



TABLE 37. Relation of yield of plant to height and tillering, and to the yield per head. 



TABLE 38.--Relation of yield per head to yield, height, and tillering of plant, and to weight of 



average Icernel. 



SUMMARY AND CONCLUSIONS. 



As between wheat kernels of the same variety raised under similar 

 conditions, those kernels having a high percentage of proteid mate- 

 rial have a lower specific gravity, weigh slightly less, and occupy a 

 smaller volume than kernels having a smaller percentage of proteids. 



As between individual spikes and individual plants, the same rela- 

 tions obtain. 



As between individual plants in different years, these relations do 

 not hold. 



The quality of high proteid content and its correlated properties 

 may be due to immaturity in the kernel, or they may belong to the 

 normal and fully ripened kernel. 



As between kernels, spikes, and plants, those kernels of greater 

 weight contain a larger weight of proteids this in spite of the fact 

 that they contain a lower percentage.
