Abstract

Of the several criteria of seed quality in oats, weight per bushel, or test weight, is most universally used. The standard test weight for oats is 32 pounds per bushel, but with present-day varieties and production practices, oats produced in the Corn Belt often exceed this value by from 3 to 6 pounds. The oat seed characteristics which have been found to be correlated with test weight arc: hull percentage, seed shape and size and plumpness and density of the caryopsis. Test weight in oats has been proven to be an inherited characteristic. Barring diseases such as rust, which may materially affect test weight, generally, there is little variety by environment interaction for this characteristic. Since high test weight in oats is a desirable characteristic, cultural practices which reduce or increase it arc of importance. This paper is a summary of test weight data of oats from a series of experiments which involved different rates and dates of seeding oats.
