The reactions of some quality wheat lines against yellow rust and stem rust reactions

Abstract

Yield potential, abiotic and biotic stress resistances and quality parameters are very important selection criterion for crop improve programme. Breeders use different tests to evaluate wheat good quality. These tests (test weight, mixographe, Zeleny sedimentation gluten rheological parameters) are based on the end-use quality objective of the breeding programmes. On the other hand rust (Puccinia spp.) disease resistances are important selection criterion improve programme. 5 bread wheat genotypes (Zeleny sedimentation (57-65 ml)., (Bezostaja-1; 56) in yield trials were developed by the Central Research Institute for Field Crops (CRIFC) Department of Quality Assessment and Food. The aim of this study was to determine the reactions of 5 winter bread wheat lines to yellow rust (YR) and stem rust (SR) disease in adult plant stage. The test materials were sown in a one meter row with 2 replications in I YR) and Seydiler, Kastamonu (for SR) locations. The test materials were screened for yellow rust artificial epidemic condition with YR (virulent on Yr2, 6, 7, 8, 9, 25, 27, Sd, Su and Avs resistance genes in Europe/World differential set) and under natural epidemic condition with SR (virulent on: Sr5, 6, 7b, 8a, 8b, 9b, 9g, 10, 30, Tmp and Mcn resistance genes). Yellow rust and stem rust developments on each entry were scored using the modified Cobb scale (Susceptible control cv. Little Club 80-100S) in July-August 2015. Coefficients of infections were calculated, and the values below 20 were considered as resistant to disease One material was resistant to YR and SR in adult plant stage. These resistance genotypes can be used in both quality and yellow rust and stem rust resistance breeding programs to stem rust reactions.
