CEREAL IMPROVEMENT SELECTION 203 



pedigreed sort from Horsfords cross bred Chevalier of 

 this country; and (3) Primus, selected out of Diamond, 

 which was an unfixed product of a cross of Chevalier 

 and Imperial, the last an erectum variety. 



Grenadier II. wheat is a selection from English Shirreff, 

 a square-head sort. Pudel wheat was isolated from 

 English Squarehead. It is from the dense-spiked, velvet- 

 chaff type, and is the hardiest pedigreed sort selected from 

 the less hardy imported varieties. The variety Bore 

 was isolated from a Probsteier wheat. It is almost as 

 hardy as Pudel, and has a very stiff straw. These two 

 wheats and Renodlad Squarehead are the three leading 

 sorts in central Sweden. 



Victory oat, a white selection from Probsteier, is the 

 leading white oat produced at Svalof (see Fig. 29). Gold 

 Rain is a yellow oat also separated from Probsteier, and 

 has the qualities of earliness, yielding power, and strong 

 straw combined. Yellow Nasgaard oat, selected from 

 Danish Island by Vestergaard of the Abed Station, Den- 

 mark, in 1899, ranks with Victory at Svalof. Great 

 Mogul, a black oat, is a pure-line selection from Tatarian 

 Black; kernels tolerably large, long, well filled, plump, 

 thin hulled, and long awned; plants very tall with un- 

 usually stiff straw.

 established variety of the Pirna plateau, in Saxony, but 

 has been improved by Steglitz of Dresden. It has long, 

 slender, thin-hulled kernels, square, well-filled spikes, 

 and is very winter hardy. Petkus rye has been bred 

 since 1881 by F. Von Lochow of Petkus in Germany. It 

 is derived from Pirna rye. It has a medium long but 

 strong and tough culm, and stands up well, a square, 

 well-filled spike of medium length, an average winter
