Biochemical mechanisms of resistance to stripe rust (Puccinia striiformis f.sp. tritici) in winter wheat (Triticum aestivum
Abstract:
Data of the experiments revealed the status of winter wheat genotypes with respect to resistance against stripe rust at adult stage. Among the twenty five genotypes evaluated, China 84-40022, Drina, Drina NS 720, Joss Cambier, Mega, Saptadhara and WW-27 were resistant; Bolal, Centruck, Golden valley, WW-23, WW-24 and WW-25 were moderately resistant and PBW-343 and Agra local were highly susceptible to stripe rust under field conditions. The proline content and total phenols maintained a highly significant negative correlation with final rust severity (FRS) in field across the wheat genotypes. Proline content and total phenols were found maximum in Mega followed by Bolal whereas minimum values for these traits were found in PBW-343 followed by Agra local.
