From Kolben a single strain, No. 0702, has been isolated which is regarded 

 as slightly superior to the original. 



Two American sorts Red Fife and Duluth have been tested. From the 

 latter several lines have recently been taken but it is yet too early to antici- 

 pate results. 



The Brown Schlanstedt wheat which, in the province of Saxony, Germany, 

 competes with the best autumn sorts in yield, has been thoroughly tested in 

 Sweden but found to be too late for that country. It is therefore proposed to 

 cross this sort with such sorts as Kolben and Red Fife with the hope of com- 

 bining some of the high yielding properties of the former with the earlier 

 maturity of the latter. 



Approximately 200 pedigree plots of spring wheat representing the pro- 

 ducts of five different crossings, all in the 4th generation, were under study 

 in the Experimental grounds at Svalof in 1910. These were as follow: 



1. 0201 X Pearl. Object t combine the good quality of Pearl with 



the high yield of the former. 



2. Pearl X Kolben. Object : to obtain a sort combining the earliness 



and rust resistance of Kolben with the very stiff straw of 

 Pearl. 



3. 0201 X Kolben. Object: to obtain a sort combining the rust 



resistance and quality of Kolben with the yield of 0201 . 



4. Kolben X 0729 (a brown-chaffed, awned.sort). Object: to obtain 



an earlier ripening sort of the Kolben type for the spring 

 wheat districts of the North. 



5. Kolben X 0740 (a common variety from Dalarne). Object: the 



same as No. 4. 



3. Oat Breeding. 



During the first years of the Association's existence the work with oats 

 as with wheat consisted in testing a large number of Swedish and foreign 

 sorts in order to obtain the best material as foundation for further improve- 

 ment. From among these sorts the following three seemed most worthy 

 of cultiviation: 



1. Probstier (sort commonly grown in the Baltic region). 



2. Ligowo, a pedigree sort obtained from Vilmorin of France and suit- 

 able for later districts where an earlier sort is required. 



3. Black Tartarian, for those districts in which black sorts are preferred. 



In oat breeding work the principle considerations are: Yield, quality, 

 strength of straw, resistance to disease and ability to thrive on a reasonable 

 variety of soils. In the central and northern districts earliness is one of the 

 most important qualities. The performance of the different sorts in regard 

 to these points is striking and indicates that a ' universal ' oat sort is not to 

 be expected in a country presenting such a variety of conditions as is found
