Near‐isogenic lines (NILs) were developed in barley ( Hordeum vulgare L.) and evaluated for resistance to barley stripe rust (BSR; incited by Puccinia striiformis f. sp. hordei ) and agronomic potential. These NILs, the BISON lines (Barley stripe rust resistance ISOgeNic), represent BSR resistance quantitative trait loci (QTL) alleles introgressed individually and in all possible combinations into a susceptible background ‘Baronesse’ (PI 568246). The lines are BISON 1H (Reg. No. GS‐4, PI 659445), BISON 4H (Reg. No. GS‐8, PI 659449), BISON 5H (Reg. No. GS‐10, PI 659451), BISON 1H +4H (Reg. No. GS‐5, PI 659446), BISON 1H+5H (Reg. No. GS‐7, PI 659448), BISON 4H+5H (Reg. No. GS‐9, PI 659450), BISON 1H+4H+5H (Reg. No. GS‐6, PI 659447), BISON 7H (Reg. No. GS‐11, PI 659452), and BISON 0‐QTL (Reg. No. GS‐12, PI 659453), and the QTL donors were BCD12 (Reg. No. GS‐2, PI 659443), BCD47 (Reg. No. GS‐3, PI 659444), and D3–6/B23 (Reg. No. GS‐1, PI 659442). The experimental lines and released line names are the same. Phenotypic data, in conjunction with genotypic data, were used to characterize QTL allele introgressions and to assess the impact of these introgressions and pyramiding on agronomic performance. The BISON lines represent valuable sources of BSR resistance in an improved background, and performance data provide useful assessments of QTL allele introgressions (alone and in combination) and quantitative versus qualitative disease resistance.
