matter of serious consequence in a country such as Sweden which suffers so 

 frequently from rain during harvest. 



The most striking characteristics of this sort, apart from the velvet 

 nature of its chaff, are its broad spikelets containing from three to four 

 kernels, the latter being white, roundish, plump and quite easily distinguished 

 from other Svalof sorts. This sort came on the market first in 1910. 



In 1905 Pudel was crossed with the common old Swedish wheat known 

 ai Swedish Velvet chaff a sort resembling Pudel somewhat in character of 

 chaff. The object of this cross is indicated later (See page 116). In 1910 

 ten of the most promising lines from this cross were in the preliminary test 

 plots and six in the small "Marker-Sown" multiplication plots. Certain of

these lines have excelled both parents in yielding tests conducted both at 

 Svalof and at Ultuna. 



Renodlad (Selected) Squarehead is also one of the most popular sorts in 

 middle Sweden, especially on the wheat soils of the Western Coast. At 

 Svalof it has been found too susceptible to a certain fungous disease (Lepto- 

 sphseria herpotrichoides) but in the above mentioned districts it stands 

 pre-eminent. 



After the hard winters of 1899 and 1901 another mass-selection of the 

 above sort was made which has given the highest average yield of all sorts 

 tested at Ultuna since that time. The quality of this sort however, is only 

 fira.
