Marker assisted pyramiding of two brown planthopper resistance genes Bph3 and Bph27 (t) into elite rice Cultivars

摘要

BackgroundBrown planthopper (BPH) is the most destructive insect in rice production. Breeding of resistant cultivars is the most cost-effective and environment-friendly strategy for BPH management; however, resistant cultivars are currently hampered by the rapid breakdown of BPH resistance. Thus, there is an urgent need to use more effective BPH resistance genes or pyramiding different resistance genes to develop more durable resistant rice cultivars.
