A note on the breeding of sugarcane varieties resistant to mosaic

The behaviour of certain Coimbatore sugarcane varieties with reference to the mosaic disease has been discussed, showing that those containingSaccharum spontaneum blood are generally resistant or at least tolerant. Preliminary data regarding the supposed correlation between bristles and mosaic resistance have been presented, which indicate that at least in certain cases there appears to be no positive correlation between the high number of bristles and disease resistance, nor in the protection supposed to be afforded by the bristles to the stomata
