Abstract

Wheat curl mite (WCM, Aceria tosichella Keifer) and WCM-transmitted wheat streak mosaic virus (WSMV, genus Tritimovirus) are devastating production constraints for wheat in the US Great Plains. Breeding wheat cultivars with genetic resistance to WCM and WSMV is a viable and economically feasible way to reduce yield loss. The objectives of this study were to (a) identify tightly linked markers for WCM resistance in the wheat cultivar TAM 112 (PI 643143) using linkage and association analysis with the 90K Infinium iSelect SNP array and genotyping-by-sequencing, respectively and (b) develop and test kompetitive allele specific PCR (KASP) single-nucleotide polymorphisms (SNPs) for marker-assisted selection (MAS) of WCM resistance. We tested 124 F5:7 recombinant inbred lines (RILs) derived from the cross of TAM 112 and the WCM-susceptible cultivar TAM 111 (PI 631352). All lines were infested with a Texas WCM collection 2 (TWCMC2) that is virulent to resistance found on the wheat-rye 1AL.1RS translocation at the two-leaf stage and were rated for symptoms on the first and second week after infestation. Linkage maps were constructed with 4890 markers, including SNPs, simple sequence repeats (SSRs), and sequence-tagged site (STS) markers covering 21 chromosomes. A WCM resistance gene present in TAM 112 (CmcTAM112) was mapped onto chromosome arm 6DS. A genome-wide association study of wheat streak mosaic (WSM) symptoms from a separate experiment in Colorado showed significant marker-trait associations at the target regions on 6DS where CmcTAM112 was located, which demonstrated the effectiveness of this gene to reduce symptom severity. Four SNPs flanking CmcTAM112 were mapped within 3.6 cM in the biparental mapping population. We developed two KASP markers that are within 1.3 cM distal to CmcTAM112 and tested in diverse germplasm. These two markers can be used in MAS for improving WCM resistance in some wheat genetic backgrounds.
