IMPEOVED STEAINS OF ROOTS 59 



of Carrots. 1 Of Banes six strains were placed in Class I., viz. 

 two Sludstrup, three Eosted, and one Ferritslev. The origin 

 of these strains has been explained, see pp. 54 and 55. 



Ferritslev IV. is the same as that described on p. 54, kept 

 up by continued selection. It has a large percentage of dry 

 matter. The roots are oblong cylindrical with a blunt lower 

 end. The top is small. 



Hosted IV. One of the sub-strains has been cultivated by 

 J0rgensen by ordinary selection. Another is derived from seed 

 which D. L. F. (i.e. the Danish Agricultural Societies' Seed 

 Supply, Eoskilde) bought in 1906 from J0rgensen and has 

 cultivated by selection. The third sub-strain belongs to the 

 firm of Trifolium, which in 1906 bought seed from J0rgensen 

 and improved the strain by selecting the 13 best of 99 families. 

 It has a larger percentage of dry matter but a somewhat 

 smaller yield of roots than Ferritslev IV., which it resembles 

 in shape. 



Sludstrup IV. In 1901 F. D. B. (i.e. the Co-operative 

 Wholesale Society of Denmark) bought seed from Michelsen 

 and cultivated it. The strain was entered and obtained 

 Class I. certificate in 1908. In 1908 56 families of the 

 strain were cultivated on the Society's farm at Lyngby and 

 the 16 best families selected. From selected roots of these 

 16 families the seed had been derived, which was entered 

 in 1910. 



Another sub-strain was derived from seed bought in 1902 

 from Michelsen. 



Percentage of dry matter somewhat higher and the yield 

 of roots correspondingly lower than those of Eosted IV. The 

 roots are well- shaped, smooth, long oval, slightly tapering at 

 the lower end. Top rather heavy. 



Of the Turnip 'Yellow Tankard two were in Class I. 



Pajbjerg IV. Chr. P. Jacobsen (Markfr0kontoret) bought 

 seed of Yellow Tankard from P. Lawson and Co., and in 1886 

 began to grow stock seed. In 1895 J. Hvidberg, of Pajbjerg, 

 bought some stock seed from Markfr0kontoret and some trade 

 seed from Lawson and selected those roots for seed which had
