ABSTRACT
Backcross lines of high yielding cultivar DWR 162 developed earlier carrying leaf rust resistance genes Lr24 and Lr28 were utilized to pyramid the two genes using marker assisted selection. Background analysis using 136 SSR markers was done to compare the genotypic background of backcrossed lines with recipient variety DWR162. Background analysis of 42 BC2F2 plants carrying both Lr24 and Lr28 was undertaken using polymorphic SSR markers to identify plants with better recovery of DWR162 background.
Keywords: Triticum aestivum L., introgression, leaf rust, foreground selection, background selection, resistance genes, molecular markers.
