Pedigree plots In the section devoted to small pedigree cultures were to be found appro xi- 



under inmsti- ma tely 200, about one-half of which consisted of pedigrees taken out of old 



l9uT mixed varieties, while the other half consisted of the products of artificial 



crossings in different generations. Of the different series under consideration 



the following may be named, the field numbers being used in each case : 



87- 91 Pedigrees out of a stock of Grey peas obtained from E. Berg, 



OJard?jo, Rattvik. 



95-106 Pedigrees out of a stock of the so-called Jemtland pea ob- 



tained from Count Morner, Birka, Tang. 



107-115 Products of artificial crossing between Capital II and Con- 



cordia 3rd generation. 



The object of this cross is to obtain a sort combining the 

 general type of plant and productiveness of Concordia 

 with the more popular shape and color of seeds (round and 

 pure yellow) of Capital II. 



116-120 = Products of artificial crossing between Solo and 0351 -3rd 

 generation. 



121-133 = Products of artificial crossing between Solo and Peluschken, 

 3rd generation. 



134-144 = Products of artificial crossing between 0351 and Peluschken 

 3rd generation. 



The object of crossing the above three green-fodder sorts 

 is to obtain if possible, still better sorts for this purpose, by a 

 better combination of certain characters. 



145-167 = Products of different crossings in the 2nd generation. 



6. The Breeding of Clovers and Grasses* 



Owing to financial limitations and to the more pressing need for active 

 work with cereals during the early years of the Association's activities, system- 

 atic work in the improvement of grasses and clovers did not begin at 

 Svalof Until about 1907. Since that time this branch of the Association's 

 operations has been in charge of Dr. Hernfrid Witte. 



Approximately 36% of the cultivated area of Sweden is devoted to 

 the production of fodder crops of which grasses and clovers constitute by 

 far the major part. The leading grasses are Timothy, Orchard grass, Meadow 

 fescue and Tall Oat grass, while in clovers the Early Red and Late Red stand 

 pre-eminent. Over twenty million pounds of grass and clover seed are required 

 annually to sow the area devoted to these crops. Of this quantity about two- 

 thirds is produced within the country, and this consists almost exclusively 

 of Late Red clover, Timothy and Alsike. The remaining one-third of the 



* The data on work with grasses and clovers which are submitted in this paper, have been obtained 

 chiefly from publications, including annual reports, by Dr. Witte.
