Summary Seven composite samples of Minnesota grown soybeans and seven individual lots of Illinois soybeans of the 1942 crop containing varying percentages of immature and frost‐damaged seeds were subjected various analyses. Increased damaged‐seed content was accompanied by a marked decrease in viability and by increases in phosphate acidity, amino‐acid acidity, nonprotein nitrogen, reducing sugars, and in the internal aerobic microfloral content of the seeds. Proximate composition of the samples within each series showed little variation. In the Minnesota series, crude fiber content slightly decreased with increasing damage but the total digestible nutrients values were essentially similar for all samples. The most severely damaged samples in each group were slightly the lowest in test weight per bushel and oil content and were the highest in oil acidity. In the Minnesota series, the iodine value of the oil tended to increase slightly with increasing damage; this is attributed to the fact that the most severe frost damage occurred in growing areas which normally produce oil of high iodine value.
