From page 5...
... Locational Variations in Composition The relative importances of region and statewithin-region variations in composition were studied by means of analysis of variance. Because of insufficient data this analysis was not made for folic acid.

... Although the size of the surveys was too limited to obtain a clear picture of the locational variations in nutritive value, certain findings seem worthy of brief mention. Protein content was lower than average in a region approximately denned by the states of Illinois, Indiana, Ohio, Kentucky, West Virginia, and Tennessee.

From page 7...
... It appears that, with the possible exception of fat, differences in nutrient composition among varieties grown in practice are not of practical nutritional importance. It is not intended to imply that nutritionally improved varieties cannot be developed by proper breeding and selection, but only that the more important commercial varieties appear to be genetically rather uniform with respect to factors determining nutritive value.
