128 BREEDING CROP PLANTS WHEAT SELECTIONS A new winter wheat, Kanred (Jardine, 1917), discovered at the Kansas Experiment Station as a result of testing out 554 head selections made from Crimean (No. 1,435 of the Office of Cereal Investigations, United States Department of Agriculture) is a rather striking example of what may be accomplished by this method of work. As an average of six years' tests, Kanred yielded 4.6 and 5.2 bu. more than Turkey and Kharkov respectively. These varieties gave best results under Kansas conditions until Kanred was found. Table XXVII shows a comparison in yield between commercial varieties and selections made from them (Love and Craig, 1918a) at the Cornell Station. TABLE XXVII. THREE-YEAR AVERAGE YIELD PER ACRE OF WINTER WHEAT VARIETIES AND SELECTIONS MADE FROM THEM Varietal selections
RESULTS OF SELECTION WITH SELF-FERTILIZED CROPS 129 tance may be improved by selection. The illustration below, taken from Williams (1916), shows clearly what has been accomplished at the Ohio Station in the way of isolating a strain with stiff straw. The three pure lines shown are selections from the commercial variety Fultz. FIG. 26. Variation in stiffness of straw in pure line selections of Fultz wheat. (After C. G. Williams.) OAT SELECTIONS The Maine Experiment Station has made somewhat extensive studies of pure lines in oats (Surface and Zinn, 1916). The yields of commercial varieties were compared with that of their respective pure-line selections. In Table XXVIII are given a part of the data reported in Maine Agricultural Bulletin 250. The average of the seven pure lines of Banner for the entire period of the test is 81 bu. per acre, while that of the commercial Banner is 79.7 bu. The average difference for the period of the test between commercial Irish Victor and the four pure lines is nearly 6 bu. per acre.
