Characterisation of wheat germplasm for slow rust resistance against Puccinia striiformis

Abstract

Thirty-seven wheat germplasm were screened under artificial epiphytotic conditions against stripe rust of wheat at University Research Farm, Chatha, during Rabi, 2013–2014 and 2014–2015. On the basis of final rust severity (FRS), AURPC (Area Under Rust Progress Curve) and CI (Coefficient of Infection), 8 genotypes ((DWR 16, HD2281, VL616, K65, UP2121, HD2329, HD2307 and Lal Bahadur) exhibited partial resistance against the disease. PCR profiles revealed co-dominant pattern with distinct fragment of 150 bp in 14 germplasm, showing the presence of Yr18 gene and 229 bp band in 16 germplasm exhibited absence of Yr18.
