Ten sugarcane varieties, PR 1059, PR 1140, PR 61-902, PR 62-258, PR 62-285, PR 64-15, PR 64-610, B 49-119, CB 49-260 and CP 52-43, were tested for resistance to ratoon stunting disease. PR 61-902, inoculated with the causal agent, produced significantly less cane and sugar per acre (approximately 31%) in plant cane, first ratoon and second ratoon crops as compared with those obtained from disease-free, hot water treated nursery stock. Therefore, it is recommendable to use only the ratoon stunting disease-free seed pieces of this variety for commercial planting in Puerto Rico.}, number={2}, journal={The Journal of Agriculture of the University of Puerto Rico}, author={Liu, Lii-Jang and Ramírez-Oliveras, G. and Serapión, J.
