After the particularly severe winter of 1891 a further thinning of the 

 above sorts was made and from the surviving plants such well known 

 pedigree sorts as Grenadier and Extra Squarehead originated. In this way it 

 was soon found comparatively easy to obtain hardier forms but unfortunately 

 such forms proved, in the majority of cases, to be inferior in other essential 

 particulars, such as yielding capacity, strength of straw and resistance against 

 rust (See Fig. 25) . The Grenadier however seemed an exception in that it 

 maintained, to a large extent, the very good yielding power of the old imported 

 Squarehead, while the hardiness was increased to some extent although not 

 sufficiently even for Skane. These three sorts became widely distributed, 

 especially in the southern parts of the country, and were without doubt 

 superior to the old commonly cultivated varieties.

 line out of former. The pure-line in this case excels the mother sort slightly in yield 

 but seems less strong in the straw. 



A great number of strains have been taken out of the old Swedish sorts 

 but the results have not been satisfactory in that no strain has been found 

 which combines hardiness and good quality with high yield and stiff straw 

 in sufficient degree. One of the best of these sorts, Svalofs Brown "Land" 

 Wheat, came on the market but as subsequent experience showed that it 

 marked no advance over the old variety, it was finally withdrawn. 



Two forms, registered under the numbers 0701 and 0516 and taken 

 from the so-called "Land" Wheat oj Skane, affords an interesting illustration 

 of how different in character, forms from an old sort may be. In a trial plot 

 of No. 0516 there was found in 1896 an aberrant type which, on propagation, 

 received the name Kotte (Cone) , a sort to which reference has already been 

 made. (See page 74). The following scheme indicates the character of
