QTL for Important Yield Traits of Sorghum-Sudangrass Hybrid

A total of 55 QTLs were detected, uniformly distributed over the 10 linkage groups (LGs), with logarithm of odds values ranging between 2.5 and 7.1, which could explain the 4.9–52.44% phenotypic variation. Furthermore, 17 yield-related relatively high-frequency QTL (RHF-QTL) loci were repeatedly detected in at least two environments, with an explanatory phenotypic variation of 4.9–30.97%. The genes within the confidence interval of RHF-QTL were annotated, and seven candidate genes related to yield traits were screened.
