|a Sheath blight (ShB; caused by Rhizoctonia solani AG1-1A) and narrow brown leaf spot (NBLS; Cercospora janseana) are among the most important diseases affecting rice production in Texas and other southern parts of the United States. Because of the high yield potential, hybrid rice acreage is continually increasing. Understanding the relative levels of resistance to ShB and NBLS in hybrids compared to those of inbreds is important for effective disease management; however, this information remains largely unknown. A comparison of the performance of hybrid rice and inbred rice was performed involving 173 hybrid and 155 inbred genotypes (cultivars and elite breeding lines) over the course of five crop seasons (2016 to 2020) and two locations in Texas. The results showed that genotype, cultivar type (hybrid or inbred), location, and their interactions had significant effects on the severity of ShB and NBLS. The ShB severity in hybrid genotypes was significantly lower than that in inbred genotypes, with an average reduction of 27% in disease severity during the 5-year, two-location evaluation. Most (53%) of the hybrid genotypes were rated moderately resistant, whereas almost all (97%) of the inbred genotypes ranged from very susceptible to moderately susceptible. Similarly, NBLS severity in hybrid genotypes is significantly lower than that in inbred genotypes. All but four hybrid genotypes exhibit immune reactions to NBLS. In contrast, 77% of inbred genotypes exhibit NBLS symptoms, with disease resistance reactions ranging from susceptible to resistant. The results demonstrate that hybrid rice is generally less susceptible to sheath blight and has a higher level of resistance against NBLS compared with inbred rice
