This work developed a novel nested polymerase chain reaction (n-PCR) assay to identify Sorghum nitidum (S. nitidum). It has been designed a set of specific n-PCR inner primers Snit5/Snit2 and outer primers Nout1/Nout2 based on a conserved nucleotide sequence of adh1-like gene of S. nitidum. Fourteen samples of sorghum were used to investigate the specificity of the primers and the n-PCR assay. The result showed that 9 samples of S. nitidum displayed a positive strong, specific amplified band at ~873 bp in gel spectra, while other relatives, including Sorghum halepense, Sorghum almum, Sorghum bicolor, Sorghum propinum and Sorghum sudanse exhibited negative amplifications. This assay was able to specifically identify S. nitidum fast and effectively, which could be applied widely in field inspection, agriculture production and plant protection.
