In another ear to row experiment, started in the year 1906 and carried 

 on for two years, even more striking results were secured. In this 

 second experiment 200 ears were planted in 1906, but only half an ear 

 to a row. In 1907, the remainder of the ear was used for seed and each 

 planted in a separate row in order to check the results secured in 1906. 

 Not all the ears yielding high in 1906. yielded high in 1907, as there 

 was some difference in the two seasons, and all ears did not seem to do 

 equally well in different seasons. However, there were four ears out of 

 the 200 that gave very high yields both seasons, and the crop received 

 from these four was saved for further test. The result of this test in 

 1908, is shown in the following table :

Bushels. 



Avg. yield of remnants, 4 best ears 70 



Avg. yield of 1907 progeny, 4 best ears 68 



Avg. yield of check plats (original stocks) 59 



Avg . yield of remnants, 9 poorest ears 56 



The 1903 Class I. selection under same conditions yielded as follows (See table I.) 



Avg. yield remnants, 5 best ears 73 



Avg. yield 1907 progeny, 5 best ears 66 



Avg. yield check plats 59 



There was a small remnant of each of these four best ears still left 

 and they gave a good yield. The 1907 progeny of these ears yielded 

 68 bushels, while the original stock from which the corn was selected, 

 yielded only 59 bushels. This shows a gain of 9 bushels per acre as a 

 result of ear to row test. Further details in regard to carrying on tests 

 in these experiments are shown in Bulletin No. 12, of the Nebraska 

 Station. 



Results of wheat breeding have been equally satisfactory and a 

 similar method has been used. In this test a large number of wheat 

 plants were first selected from a field of Turkey Red in 1902. Each 

 plant was planted separately. The product of each plant was again 

 planted separately the next year and so on for several years until quite 

 a supply of seed had been secured from each original plan, and the 

 product of each plant is called a pure strain. However, as the work 

 went on from year to year, those pure strains which did not seem 

 promising, were discarded. By the fall of 1906 we had enough seed from 

 26 of these pure strains to plant in large field plats. Each strain was 

 planted in a tenth acre plat, and in most cases repeated two or three 

 times. Every fifth plat was made a check plat — this plat being phinted 

 with the original Turkey wheat from which selection was made. This 

 test has been carried on for four years in the field plats and has given
