Abstract

Abstract: We assessed inheritance of resistance to sugarcane brown rust ( Puccinia melanocephala ) in selfing F1 populations of wild sugarcane germplasm Erianthus rockii 'Yundian 95-19' and E. rockii 'Yundian 95-20'. We tested parent and selfing F1 individuals for the brown rust resistance gene, Bru 1, that has been shown to confer resistance to brown rust in sugarcane. The Bru 1 gene was not detected in E. rockii 'Yundian 95-19', E. rockii 'Yundian 95-20' or their selfing F1 individuals, and we found there was segregation of resistance in the two selfing F1 populations (segregation ratio: 3:1). The results confirmed resistance in E. rockii 'Yundian 95-19' and E. rockii 'Yundian 95-20' to sugarcane brown rust is controlled by a novel, single dominant gene.
