【 摘 要 】
The red spider mite Tetranychus urticae (C.L. Koch, 1836) is an essential cassava pest, particularly in dry regions, which may cause a considerable yield loss. To reduce the damage of this pest, chemicals are applied in the field, possibly leading to adverse environmental effects. Therefore, using resistant cultivars is considered an effective and environment-friendly alternative. The study was conducted on 11 cassava clones and four cultivars (as control) during the 2016 planting season to identify the resistant clones to red spider mites in a greenhouse, producing a high yield in the field. The greenhouse experiment was conducted at ILETRI (Indonesian Legumes and Tubers Crop Research Institute). In contrast, the field experiments were explored at the Jambegede research station, Malang district, East Java Province, Indonesia. Both trials were arranged in a randomized block design with three replications. The results showed that there were four clones (CMM 03036-7, CMM 03036-5, CMM 03038-7, and CMM 02040-1), and one cultivar (Adira 4) in cluster 3 were categorized as –1moderately resistant and resistant groups to mites and had high tuber yields (above the average yield, > 41.12 t ha ). At a high mite population, all clones or cultivars will be attacked by mite pests; however, the clones (CMM 03036-7, CMM 03036-5, CMM 03038-7, and CMM 02040-1) exhibited the tolerance to red mite attacks. These results indicate that these clones are promising approaches for collecting resistant cassava cultivars against red mites.
