26 BULLETIN 829, U. S. DEPARTMENT OF AGRICULTURE. 



Figure 5 shows a row of Kavangire cane on the left; a susceptible 

 variety, G. C. 1070, at the center; and a diseased but tolerant variety, 

 Java 56, on the right. Unfortunately, the Kavangire variety is a 

 long-season cane and therefore not suitable for conditions inLouisiana. 

 The possibility of breeding inore early maturing varieties from these 

 parents is being investigated. 



Several of the broad-leaved varieties of cane originated at the 

 Sugar Cane Experiment Station at Audubon Park, La., appear to be 

 immune. Although equally exposed to the contagion, no individuals 

 of these varieties have become affected, while practically every plant 

 of the scores of other varieties surrounding them is diseased. They 

 have been under observation for too short a time, however, to 

 demonstrate that their apparent immunity is permanent.
