Oats generally are considered to be less heat tolerant than other cereal crops. Coffman found that heat resistance in oats was correlated with winter hardiness, and that early maturing winter and spring varieties were usually more heat resistant than midseason or late maturing varieties. Winter oat varieties with fine culms were the most heat resistant. Maximum resistance to killing injury occurred when the plants were about 50 days old, which corresponded to the early boot stage. Resistance to high temperatures was found to be an inherited character and was independent of disease resistance. The present study was initiated to determine the effect of abnormally high temperatures, which may occur for short periods during the spring, on the production of mature oat kernels.
