Practice of Plant Breeding 
famous examples of the same sort were Rimpau’s selected 
varieties of the rye, which have recently not only dis- 
placed all others amongst his German neighbours at 
Schlanstedt, but have invaded France and beaten out 
of the field many of the older French races.’ 
But even by selection of the best plant in a large field 
of corn, one cannot produce the very best results. It 
is necessary to select the best grain of corn in the 
best ear, This was first done by Hallett of Brighton 
many years ago. He chose the best kernel of the best 
ear of wheat, 
The plant which sprang from it had 47 grains in one 
particular ear. Again choosing the best kernel, he got 
79 grains in the second year, and in the third year no 
less than go grains. His strains were a very great 
success, and enormously improved the British harvests 
of his time. Exactly the same method has been found 
advantageous by Dr. Nilsson of Svaléf in Sweden. 
At the Ontario Agricultural College, Professor Zavitz 
has had some remarkable triumphs by using this system. 
One selected grain (the very best amongst ten thou- 
sand) of black Jannette oats, sown in 1903, produced in 
1905 over 100 bushels of grain and no less than 8748 
pounds of straw.”
