Among the techniques for control of plant diseases caused by viruses, the use of resistant varieties is one of the strategies recomended to obtain an integrated pests and diseases management. Our aim was to evaluate resistance of five genotypes of Capiscum annuum to Texas pepper geminivirus var. Coahuila. An incubation period of TPGV- Coah. in the genotypes at seedling stage ranged from 10.43 to 12.4 days. The most promising results were: Tampiqueño 74 and the line 2LP-S 294, whereas at flowering it ranged from 10.5 to 27.3 days so the most out standing line was La-S- 293. The resistance of the genotypes to TPGV- Coah showed differences at the fenology stage (inoculated); The most promising genotypes at the inoculated seedling stage were Tampìqueño 74 and criollo, at flowering the criollo and the lines 2LPS-294 and LAS-293 were the best ones, wheres at the Ejido La Leona the best lines turned out to be 2LPS- 294 and LA-S-293; finally these two lines and Tampiqueño 74. were by far the best ones at the Ejido La Gamusa.
