Identification and Mapping of QTL for Stripe Rust Resistance in the Chinese Wheat Cultivar Shumai126.
Plant Dis. 2022 Apr; 106(4):1278-1285.PD

Abstract

Stripe rust, caused by Puccinia striiformis f. sp. tritici, is a damaging disease of wheat globally, and breeding resistant cultivars is the best control strategy. The Chinese winter wheat cultivar Shumai126 (SM126) exhibited strong resistance to P. striiformis f. sp. tritici in the field for more than 10 years. The objective of this study was to identify and map quantitative trait loci (QTL) for resistance to stripe rust in a population of 154 recombinant inbred lines (RILs) derived from a cross between cultivars Taichang29 (TC29) and SM126. The RILs were tested in six field environments with a mixture of the Chinese prevalent races (CYR32, CYR33, CYR34, Zhong4, and HY46) of P. striiformis f. sp. tritici and in growth chamber with race CYR34 and genotyped using the Wheat55K single nucleotide polymorphism (SNP) array. Six QTL were mapped on chromosomes 1BL, 2AS, 2AL, 6AS, 6BS, and 7BL, respectively. All QTL were contributed by SM126 except QYr.sicau-2AL. The QYr.sicau-1BL and QYr.sicau-2AS had major effects, explaining 27.00 to 39.91% and 11.89 to 17.11% of phenotypic variances, which may correspond to known resistance genes Yr29 and Yr69, respectively. The QYr.sicau-2AL, QYr.sicau-6AS, and QYr.sicau-6BS with minor effects are likely novel. QYr.sicau-7BL was only detected based on growth chamber seedling data. Additive effects were detected for the combination of QYr.sicau-1BL, QYr.sicau-2AS, and QYr.sicau-2AL. SNP markers linked to QYr.sicau-1BL (AX-111056129 and AX-108839316) and QYr.sicau-2AS (AX-111557864 and AX-110433540) were converted to breeder-friendly Kompetitive allele-specific PCR (KASP) markers that would facilitate the deployment of stripe rust resistance genes in wheat breeding.
