IMPROVED STRAINS OF ROOTS 61 



a large yield of roots but a low percentage of dry matter. The 

 roots are ovoid in shape with a blunt lower end. The top is 

 small with fine leaves. 



Stryn(f) V. is derived from seed bought in 1898 from Markfr0- 

 kontoret, to which firm the seed had come from P. Lawson. 

 The strain has been cultivated by Rasmus Kold, Stryn0, 

 Rudk0bing, since 1898 and carefully selected. It has a higher 

 percentage of dry matter than Lille Taar0je and a very much 

 larger yield of roots. The roots are somewhat longer and the 

 top rather larger. 



Sludstrup V. A sub-strain of Michelsen's Sludstrup came 

 in Class I. in 1908. The firm of L. Daehnfeldt, Odense, bought 

 seed of it in 1909, and this was cultivated by families, and 

 selected first 14 out of 120, then 4 out of the 14. Each of the 

 four gave again 10 families, of which 3 or 4 were kept. In 

 shape and character like Sludstrup IV. 



Tystofte V. A strain probably derived from the Vilmorin 

 Barres and cultivated from the early nineties by P. Nielsen, and 

 after him improved by family selection. It is like Sludstrup 

 as regards dry matter but yielding rather more. Also like it 

 in shape and top. 



Pajbjerg V. J. Hvidberg in 1909 bought seed of the same 

 sub- strain as mentioned under Sludstrup V. Of 100 families 

 one, No. 55, was selected in 1910 and eight roots of it planted 

 for seed. From these the strain has been developed and 

 differs so greatly from the original Sludstrup that it has 

 deserved a new name. It has a larger percentage of dry 

 matter than any of the other strains but a correspondingly 

 lower yield of roots. The shape is oblong with a blunt lower 

 end, the top is large. 



Of the Swedes six came in Class L, three Olsgaard, two 

 Pajbjerg, and one Lyngby. 



Olsgaard V. The seed of this Swede was probably in 1886 

 supplied by the firm of Hurst and Son, London. The strain was 

 in Class Lin 1904, 1908 and 1909. From 1902 to 1910 family 

 selection was used. 



Another strain is derived from seed which R. Wiboltt bought 

 in 1905 and 1906 and improved by family selection. 



Pajbjerg V. This strain, belonging to J. Hvidberg, was in
