Abstract

Fifty wheat varieties were screened under artificial epiphytotic conditions against stripe rust of wheat during Rabi, 2013-14. On the basis of final rust severity (FRS), AURPC (Area Under Rust Progress Curve), r (Infection Rate) and CI (Coefficient of Infection), 10 lines exhibited partial resistance against the disease. PCR profiles of fifty wheat varieties by the allele-specific primer (cssfr1) revealed distinct fragment of 517 bp in 23 varieties indicating the presence of Yr18 gene. Wheat varieties, PBW 343, DPW 621-50, RSP 561 and HD 2967 were used for testing five fungicides viz., Amistar Top, Quadrix, Score, Folicur and Tilt, each at 0.1 percent concentration. Amistar Top was found most effective in reducing the disease severity of stripe rust in PBW 343, followed by Quadrix, Score, Folicur and Tilt. The application of these fungicides also showed a significant increase in the grain yield, with maximum increase (33.58%) by Amistar Top in HD 2967 followed by Quadris, Score, Folicur and Tilt.
