Sugarcane streak mosaic virus (ScSMV) Resistance Evaluation of Sugarcane Varieties

Sugarcane streak mosaic virus (ScSMV) is the most important viral disease of sugarcane in Indonesia with distribution almost all commercial plantations. The causes significant yield losses both cane tonnage and sugar yield. use resistant varieties best approach for controlling diseases. This study aims to investigate resistance response several introduced against ScSMV a glasshouse condition impact infection on chlorophyll proline content leaves. plants were inoculated using inoculum one month after planting an abrasive pad rubbing method. Disease incidence severity was observed at week 4-12 inoculation variety levels classified based incidence. Confirmation done by RT-PCR. Spectrophotometer used measure dual wavelengths 645 663 nm, 520 nm. results showed that tested susceptible ScSMV. There are six highly varieties, namely SRA 1, 2, N 10-4, 10-7, N10-9, 10-13, but these still require be field scale. generally decrease content. However, physiological effect needs further investigation.
