The Rp gene is qualitative and exhibits a high level of resistance to a specific P. sorghi race, and the resistance allele of Rp genes can be easily fixed into the breeding materials, but the resistance of Rp genes in some hybrids could break down due to the emerging P. sorghi race or multiple races caused infection happened in natural field condition (Zheng et al., 2018; Kibe et al., 2020). This evidence concerns the gene BLOC1S3 and infection.
