a Record of only one year. Where no record is available the breaking-strain score of the check is inserted. 



Of those that appear superior to the check, Selection ISTos. 1812, 

 1903, and 1914, only No. 1914 can be considered, for Selection Nos. 

 1812 and 1903 have a low seed vitality. Selection No. 1914 com- 

 pares favorably with the check; it has good seed vitality and is 

 somewhat taller; it has fine stems and very little basal branching. 

 The advantage appears, however, to lie with the check, for Selection 

 No. 1914 is more inclined to lodge than the check, and its resistance 

 to wilt is not well established. 



The second group, consisting of those that appear about equal to 

 the check, contains Selection Nos. 1910, 1901, and 1926. All of these 

 grade under the check on total score, but appear equal to the check 

 when the percentages allotted to resistance to wilt and lodging are 

 subtracted. Selection No. 1910 is A^ery resistant to Avilt, but has 

 coarse stems and develops more basal branching than any of the other 

 tall selections. Selection No. 1901 comes nearest to the check in this 

 group, because of its extra-long stems, but it has a low seed vitality 

 and its stems are slightly coarser than those of the check. Selection 

 No. 1926 has very fine stems, even finer than those of the Blue-Blos-
