fertility at each of three locations 1937-41 (E. S. R., 89, p. 212) showed that in
general wheat quality improves as soil fertility increases. Wheat produced on wellfertilized
plats was stronger in gluten, lower in carotenoid pigments, and higher in
flour yield than that on plats low in fertility. Variety caused greatest variations
and had most influence in producing differences in components of quality studied.
[Evaluating quality of wheat varieties] (Cereal Chem., 21 (1944), No. 1, pp.
38-64, illus. 8).-Papers in this group concerned with evaluating the quality of
wheats by means of the mixograph include Varietal, Station, and Seasonal Effects

How wheats behave in competition with one another, L. R. WALDRON (North
Dakota Sta. Bimo. Bul., 6 (1944), No. 6, pp. 7-14).-Group B of five varieties of
wheat did best when grown competing in alternate rows with the lower yielding
group A of five varieties, especially in April 17 and May 3 seedings. Group A
wheats, however, did best when not competing with group B wheats with the above
seeding dates. The different types of competitive effects were measured in terms
of yield, in number of heads per meter of row, and in milling and baking behavior.
As a practical conclusion, it is suggested that a wheat which can stand up under
strong competition with other varieties is probably able to maintain its yielding
capacity in competition with weeds, or other unfavorable conditions, better than
a less vigorous wheat. Wheats apparently must be tested for behavior under

The effect of rains on mature wheat, C. O. SWANSON (Northwest. Miller, 219
(1944), No. 2, Sect. 2, pp. 6a-9a).-Experiments at the Kansas Experiment Station
in which wheat was exposed to light rains and to artificial wetting showed that
important changes in physical properties take place when wheat is wetted by rain
after it is once dried. The test weight is lowered, exteriors of the kernels become
a dull yellow in color, and the endosperm is changed from a vitreous to a mealy
condition. Varietal differences in resistance to change due to exposure were
evident. These changes, however, do not bring about any decrease in flour yield or
impair flour quality. Loaf volumes and loaf textures were as good from the samples
subjected to rains as were those of loaves made from flours of wheats not
subjected to rain.
Factors that influence the physical and other properties of wheat.-V, Effect
of frequent rains accompanied by storms on Blackhull, Chiefkan, and Tenmarq,
C. 0. SWANSON. (Kans. Expt. Sta.). (Cereal Chem., 21 (1944), No. 2, pp.
126-140, illuzs. 1).-Frequent rains accompanied by storms during heading and
ripening of wheat had the same general effects of the smaller rains mentioned above.
Greater mechanical losses in the field caused by the larger rains were not reflected
in wheat quality.
Factors that determine wheat protein, M. A. MCCALL. (U. S. D. A.).
(Northwest. Miller, 219 (1944), No. 11, Sect. 2, pp. 3a, 7a-lOa). -Reasons for
variation in protein content of wheat are discussed with particular consideration to
climatic and regional differences, type and variety of wheat, soil fertility level,
