Durable resistance based on partial resistance is an important and effective way to combat yellow rust (Puccinia striiformis). The present study was carried out during Rabi 2016-17 and 2017-18 to reveal variability for field-based partial resistance to yellow rust among different genotypes, F1, F2and three-way crosses grown at University Research Farm, SKUAST-Jammu. Partial resistance screening was screened through Final Rust Severity (FRS), Area under Disease Progress Curve (AUDPC), Infection Rate (r), Coefficient of Infection (CI) and Relative Area under Disease Progress Curve (rAUDPC). IC 535352 genotype was found to be resistant than other genotypes with 4 % Coefficient of Infection (CI). Strong association was found between Area Under Disease Progress Curve (AUDPC) and Coefficient of Infection (CI) while too weaker association reported between Coefficient of Infection (CI) and Infection Rate (r). The present study revealed enough diversity regarding slow rusting behavior and yellow rust resistance ranging from resistant to susceptible lines. Thus, FRS, AUDPC, CI and r are suggested to be useful for screening partial resistance to stripe rust.
