Fig. XXX. Table of yields of leading Autumn wheat sorts of Svalo'f 1890-1909 



(22, p. 23). 



Pedigree ^ n * ne experimental grounds in 1910 there were between 300 and 400 



plots under pedigree plots of autumn wheats, practically all of which belonged to different 

 investigation, crossings. Each of these crossings was made with a definite practical object 

 in view. According to the present system these plots are numbered con- 

 secutively. Thus in 1910, the first plot bore the field number 132 and the 

 last 491 as follows: 



Field Numbers in 1910: 



0234 Selected Squarehead. 



0290 Extra Squarehead II. 



0406 Bore. 



0415 Sun. 



0501 Grenadier II. 



.... Tystofte Smaa wheat. 



.... Tystofte Stand wheat. 



0290 X Stand-Up (2nd generation) . 



Object of cross. To combine the higher yield which the 

 Stand-Up is capable of giving during favorable years with 

 the greater hardiness of 0290. Also to combine the shorter 

 straw of Stand-Up with the stronger structure of 0290. The 

 latter sort is normally strong, but is too long to allow of 

 maximum strength. 



145-146 = 0501 X Stand-Up (2nd generation). 



Object. Same as in last mentioned crossing.
