STUDIES ON OAT BREEDING. I9I 



while the Imported Scotch gave the smahest relative amount of 

 straw. 



The weight per measured bushel is shown in Table 12. The 

 Regenerated Swedish Select and the Victor gave the highest 

 average weight, about 41 pounds per bushel. The Kherson and 

 the Imported Scotch gave the lowest weight per bushel. These 

 were still well above the legal weight of 32 pounds. It is of 

 interest to note that the Kherson shows a progressive increase in 

 its weight per bushel for the four years that it has been grown 

 in this state. 



In addition to the eleven varieties tested for four years, three 

 varieties have been tested for three years ; eight varieties for 

 two years ; and one variety for one year only. Two or even 

 three years is too short a time to get a reliable measure of the 

 yielding ability of a variety. However the data for the yields 

 of these varieties are summarized in Table 10. 



Of the eight varieties introduced in 1912 seven were from 

 Canada and the middle west. None of these varieties gave 

 satisfactory yields in 19 12 although a number of them did very 

 well in 191 3. The eighth variety, the Early Pearl, originated 

 in Maine and it yielded very well the first year. 



These data indicate that possibly there is an advantage in 

 having varieties that are acclimated to the conditions under 

 which they are to be grown. 



Of the varieties which have been tested for four years the 

 Irish Victor, Imported Scotch, Lincoln and Prosperity have 

 made the best showing. With the exception of the Imported 

 Scotch there appears to be but little choice between these varie- 

 ties. The Imported Scotch has shown much less variability in 

 respect to all its characters (with the exception of straw weight) 

 than any of the other varieties. This is true both of inter-and 

 intra-seasonal variation. Under the conditions of seeding and 

 growth at Highmoor this variety can be expected to produce a 

 little over 60 bushels per acre every year. The chief objections 

 to this variety are its relatively small weight per bushel and the 

 yellow color of its grain. This latter objection is not very seri- 

 ous although yellow oats do not meet with so much favor on 

 the market as the white varieties.
