Abstract


Leaf Rust (Puccinia triticina Roberge ex Desm f.sp. tritici ) formly known as brown rust, is a potential threat to wheat crop all over the world. Thirty varieties were evaluated in field under randomized complete block design (RCBD in Faisalabad (Pakistan) during 2010-11.  Four cultivars (Fareed -08, FSD -08,  Lasani-08,  V-02192, V4178 ), were found immune, eight (Blue silver, Chakwal-85, Fareed-06, Sehar -06, Shafaq-06, Iqbal-2000, V- 04030, V-07194 ) resistant, five (Chenab-2000, V-04179, V-05152, V-5153) moderately resistant, four (Chenab-2000, V-04179, V-05152, V-5153) were moderately resistant to moderately susceptible. Inqilab-91, V-03094, V-05155, V-04022 were moderately susceptible. One variety (V-032860) showed moderately susceptible to susceptible response while five cultivars, (FSD-85, Kohistan-97, Pak-81, V-06096) showed susceptible reaction. In the second experiment (Pot exp.) by using CRD thirty varieties were screened. Two cultivars (V-02192 and Lasani-08) were immune. Three varieties/lines (V-04030, Sehar-06, and FSD-08) were resistant. Two cultivars (V-04178 and Freed-06) were moderately resistant. Six varieties/lines (Punjab-76, V-07194, Sehar-06, Iqbal-2000, Shafaq-06 and V-05153) were moderately resistant to moderately susceptible. Four varieties (V-04022, V-04030, Punjab-96 and Chakwal-85) were moderately susceptible. Only one line (V-032860) was moderately susceptible to susceptible. The present study clearly emphasizes that resistant varieties should be cultivated under farmer’s field conditions to avoid the yield losses from leaf rust.
