Abstract
Dirty panicle disease is one of the most important diseases that can cause yield losses in rice production. Despite the severity of the disease the molecular basis of resistance to the pathogen is poorly understood. Using QTL-seq with an F2 population we identified three genomic regions on chromosomes 1 9 and 10 namely qDP1 qDP9 and qDP10. These regions are significantly associated with resistance to dirty panicle disease caused by two fungal pathogens Bioplaris oryzae and Cirvularia lunata. qDP1 was significantly associated only with resistance to B. oryzae whereas qDP9 and qDP10 were significantly associated with both B. oryzae and C. lunata. We also developed KASP markers for each QTL detected and validated them in the F2 population. The markers were able to explain phenotypic variation in a range of 5.87�.20%. Twelve potential candidate genes with annotated functions as resistance-related genes were proposed. These candidate genes include those encoding RLK MATE WAK NBS-LRR subtilisin-like protease and ankyrin repeat proteins. The results of this study provide insights into the genetic mechanism of dirty panicles in rice and will be useful for future breeding programs for dirty panicle resistance. This is the first report of QTLs associated with resistance to dirty panicle disease in rice. ? 2023 by the authors.
