attention to breeding wheat for quality Recently results
Investigations for the improvement in nitrogen of
wheat have appeared along the method of neselecon while
he possibilities for improvement of wheat by hy
orldzaton will depend whether baking strength is

the problem of improving the nitrogen to
hybrid wheats that have given promise milling wheas but

selections result lower nitrogen crop than the
