Identification of brown rust resistance in the field and detection of the Bru1 gene in sugarcane varieties

Abstract: The aim of this study was to assess brown rust resistance in 60 new sugarcane varieties bred by the China Sugarcane System recent years and 34 major cultivated growing areas China. these investigated field, molecular markers were used detect rust-resistance gene Bru1. results field survey showed that 66 (70.21%) 94 highly resistant moderately resistant, 28 (29.79%) susceptible susceptible. Bru1 detected 54 (57.45%) varieties. Seven five did not carry Bru1, suggesting they other genes associated with resistance. This provides a scientific basis identifies disease-resistant germplasm for selection plants production.
