It was not possible to distinguish between 2 cultures of races 17 and 29 on the standard rust differential wheat varieties at the recommended greenhouse temperature of about 75[degree]F. From among these varieties 5 were found that produced differential reactions to the 2 cultures but only at temperatures of 75[degree]F and lower. Of these 5 varieties Bowie gave the sharpest differential reaction, especially at a temperature of 70cF.
