Seed Wheat. 



grain shown in Fig. 31 as in Fig. 32. The quality of the grain shown in Fig. 31 is 

 manifestly the better. 



The figures and illustrations do not tell the whole story, however, for apart from the 

 manner in which the samples grade up there is the difference in the appearance of the 

 samples. The sieves separate the grains according to size alone, taking no account of 

 plumpness. As a matter of fact, when two samples, one grown from small seed and the 

 other from large seed, are placed side by side, it is usually possible to see that the 

 sample derived from the large seed is the plumper and better sample. The difference is 

 a rather small one, but is usually distinctly perceptible, and is one that would not be 

 overlooked by an experienced buyer of wheat. 



This defect in plumpness has to be added to that of size shown in the illustrations to 

 fully appreciate the inferior market quality of the grain derived from small seed. 



Hence we have in a grain-crop derived from small seed not only a lower yield of grain, 

 but a decided inferiority in quality.

As might be expected from all this, the weight per bushel of the grain crop from small 

 seed is less than that from large seed. As derived from numerous tests made during 

 these experiments the difference is a small one, but it is very constantly in favour of the 

 crop derived from the large grain, which is found to weigh from a small fraction of a 

 pound up to a pound a bushel more than that derived from the small grain. 



TABLE SHOWING SUPERIORITY OF CROPS OF GRAII* FROM PLANTS FR.OM LARGE SEED. 



In this table the three crops of grain are arranged under the variety name in three 

 columns the crop from the large seed in the first column, the crop from the medium-sized 

 seed in the second column, the crop from the small seed in the third column. Thus, under 

 the name White Velvet, we find three columns, entitled large, medium, small. In the 

 first column, opposite each grade number, will be found the percentage by weight of 

 that grade in the sample of grain yielded from the planting of large seed. Similar 

 results are found in the second and third columns for the crops from the plantings of 

 medium-sized and small seeds. Reading horizontally in the three columns, it will be 

 seen that the sample yielded from the planting of large seed contained 18*6 per cent, of 

 the 3'25 grade ; while the sample from the medium seed contained only 13'9 per cent.; 

 and the sample from the small seed only 12 '4 per cent. Similar figures are tabulated 

 for the other varieties, i.e., Allora Spring and Hudson's Early Purple Straw. 



These figures, showing the greater proportion of large grains in the crops raised from 

 large seed, are indicative of a higher market value for those crops. It is not necessary 

 to grade the samples in order to detect this difference, as it can be easily seen at a glance. 

 The grading, however, enables us to measure the difference -and show that just in 

 proportion as the seed is large and plump so will be the predominance of large seed in 

 the progeny.
