TRIALS OF SELECTIONS FROM ALL HEAD EARLY^ON YELLOWS-SICK SOIL 
A. View of Drummond plot, Racine, Wis., in 1921. The row in the center was planted with 
commercial All Head Early; note that the yellows disease has killed nearly every plant. 
The next row to the left is a first generation selection from All Head Early, XL-20-1. Note 
the nearly complete stand as compared to the control. The remaining rows to the left are 
the resistant Late Wisconsin Hollander. The first two rows to the right of the control are 
strains of the resistant Maryland Flat Dutch 
B. View of the Broesch plot, Racine, Wis., in 1923. The row in the center is commercial All 
Head Early; note that here, as in field A, this is nearly destroyed by disease. The first row 
at the left of the control is the progeny of a single plant (XL-22-1) selected from the All Head 
Early selection, XL-20-1, tried in 1921 and shown above in A. The second generation selec¬ 
tion proved to be highly resistant, but is of undesirable type, being too late in maturity, 
too peaked as to head shape, and too yellowish green as to color. The first row on the right 
of the control contains second-generation selections from All Head Early (XL-23-1 to 5), 
belonging to a line distinct from those noted above. These strains are also highly resistant 
and approximate more closely the desired type. These give promise of commercial value
