storage to prevent '' yellow grains." Unless the fungi are killed in the 

 process, drying will not serve the desired purpose, as the fungus caus- 

 ing the stains will start developing again if the grain is placed in a 

 warm, damp place. 



The most promising solution for these troubles seems to be in the 

 eventual development of resistant strains and varieties. Table 2 

 shows that some varieties are much more susceptible than others when 

 grown under the same conditions. The varieties which showed the 

 heaviest attacks in these tests are as a. rule less hardy and poorer 

 yielders in the field. These seed-infesting fungi evidently have played 

 their part in the varietal selection work where hardy varieties have 

 resulted. With a thorough knowledge of these troubles the problem 

 of breeding hardy strains of rice would be somewhat simplified.
