An experiment comprising of 49 exotic wheat germ plasm accessions was conducted at AridZone Research Institute, Dera Ismail Khan, Pakistan under rainfed condition during 2013-14 for theirresistance against stripe rust disease. The trial was laid out in randomised complete block design with threereplications. All entries were planted in a four-row plot with 3 m for row length and 25 cm for space amongrows. A local susceptible check was repeatedly sown after every 10 test entries. The crop was maintainedunder rainfed conditions. Results revealed that all the exotic genotypes were genetically divergent inresponse to stripe rust disease. The disease score ranged from very highly susceptible to very highlyresistant. Among 49 exotic lines, 27 exhibited from very highly resistant while 10 were susceptible to veryhighly susceptible.
