Provided is a tobacco plant or germplasm resistant to TSWD, which comprises a short RTSW introgressed segment, wherein at least part or entire of the sequence set forth in SEQ ID No.34 is deleted in the short RTSW introgressed segment as compared to the RTSW introgressed segment of tobacco ‘Polalta’. Also provided is a method for screening said tobacco plant or germplasm, in which a tobacco plant or germplasm resistant to TSWD carrying a short RTSW introgressed segment is obtained by detecting NaChr4_2M, NaChr4_8M, NaChr3_62.6M and NaChr3_64.6M linkage drag locus markers. Compared with ‘Polalta’, the tobacco plant or germplasm provided by the invention not only has TSWD resistance, but also reduces or removes linkage drag.
