these forms and gives the pedigree of Cone together with its present 

 place in breeding work: 



A few fairly high yielding strains have been taken from the old Swedish 

 varieties, but these have proven less hardy than the latter. This fact among 

 others, has led to the conclusion that these forms are in many cases at least, 

 the products of natural crossing between such high yielding but more delicate 

 sorts as Squarehead and English Stand-Up, etc. The most noteworthy sort 

 belonging to this' category is Sun. (See p. 113). 



From the imported English Squarehead wheat there have been isolated 

 a number of strains which have proven even more winter-hardy than those 

 already described (Grenadier and Extra Squarehead) . Of these the sort 

 known as Pudel (See Fig. 12) is the most valuable. While not so hardy 

 as the old Swedish varieties, Pudel nevertheless combines a sufficient degree 

 of hardiness with yield and other qualities to enable it to largely displace 

 the old "land" sorts. The relationship between the above sorts in respect 

 of hardiness together with the origin of each is indicated in the following 

 diagram : 



* This crossing has not only given the highest average yield for the past four years, but has been 

 most resistant against rust. It is still lacking in quality however, so will be subjected to repeated crossing 

 in the hope of obtaining quality of a higher degree.
