“…Sixteen entries were resistant both at the seedling and adult-plant stages (ETBW8905, ETBW8800, ETBW8917, ETBW8823, ETBW8827, ETBW8583, ETBW8705, ETBW8486, ETBW8491, ETBW9015, ETBW9470, ETBW8260, ETBW8437 and ETBW8387, DANDA'A and HUL-LUKA) suggesting that these entries might carry either a novel resistance gene(s) or an effective combination of resistance genes. Similar to our study, Zheng et al (2017) obtained multiple gene combinations among Yr resistance genes in Chinese wheat materials that were effective in the field. Chen (2013) suggested that combinations of all stage resistance genes such as Yr5 or Yr15 and HTAP resistance genes such as Yr18, Yr29, Yr36, Yr39, Yr52, Yr59 and Yr62 should be incorporated in breeding material to develop wheat cultivars with strong and durable resistance.…”

Stripe rust caused by Puccinia striiformis f. sp. tritici (Pst) is one the most important diseases of wheat in Ethiopia and worldwide. To identify resistance genes, 90 bread wheat lines and 10 cultivars were tested at the seedling stage against one Pst race from Ethiopia and six races from China as well as evaluated for the stripe rust response in an inoculated field nursery at Yangling, Shaanxi province and in a naturally infected field in Jiangyou, Sichuan, China. Resistance genes were postulated using molecular assays for Yr9, Yr17, Yr18, Yr26, Yr29, Yr36, Yr44 and Yr62. Of the 100 entries tested, 16 had all stage resistance to all races. Molecular markers were positive for Yr9 in five genotypes, Yr17 in 21 genotypes, Yr18 in 27 genotypes, Yr26 in ten genotypes, Yr29 in 22 genotypes, Yr36 in 12 genotypes, Yr44 in 30 genotypes, and Yr62 in 51 genotypes. No line had Yr5, Yr8, Yr10 or Yr15. Complete or all stage resistance was observed in genotypes carrying gene combinations Yr9 ? Yr18 ? Yr44 ? Yr62, Yr29 ? Yr62 ? Yr26 and Yr9 ? Yr17 ? Yr26 ? Yr44 ? Yr62. The results are helpful for developing wheat cultivars with effective and more durable resistance to stripe rust both in China and Ethiopia.

“…Yr36 contain a kinase and a putative START lipidbinding domain and confers broad resistance to stripe rust at relatively high temperature (Fu et al 2009). Zheng et al (2017) also reported that few of the 672 wheat accessions tested by them had Yr36. In our study, Yr44 was found in 30% of the entries using the STS marker pWB5/pWN1R.…”

“…In the present study, Yr4 exhibited an ACI of 50, which may indicate that this gene is no more effective if it is used alone. Yr10 originated from bread wheat and is located on the short arm of chromosome 1B (It is one of the resistant genes that confers high resistance to Pst races in Pakistan (Farrakh et al, 2016) and China (Zheng et al, 2017). In Ethiopia, a yellow rust severity as high as 40% was recorded on the differential lines that possessed this gene.…”

“…In contrast, genes conferring APR are usually non-racespeci c [15]. Combining APR and ASR genes is an important approach to develop new wheat cultivars with adequate durable resistance [11,16,17]. To date, formally designated Yr genes for stripe-rust resistance number to Yr83 and more than 100 temporarily named Yr genes or quantitative trait loci (QTLs) have been reported [18][19][20].…”

Background:Stripe rust, caused by the fungal pathogen Puccinia striiformis f. sp. tritici (Pst), is a serious foliar disease of wheat. Identification of novel stripe-rust resistance genes and cultivation of resistant varieties are considered to be the most effective approaches to control this disease. In this study, we evaluated the infection type (IT), disease severity (DS) and area under the disease progress curve (AUDPC) of 143 Chinese wheat landrace accessions for stripe-rust resistance. Assessments were undertaken in five environments at the adult-plant stage with Pst mixture races under field conditions, in addition, IT was assessed at the seedling stage with two prevalent Pst races (CYR32 and CYR34) under controlled greenhouse conditions. Results:Seventeen accessions showed stable high-level resistance to stripe rust across all environments under field tests,while four accessions showed resistance to the Pst races CYR32 and CYR34 at the all-stage.Combining phenotypic data from the field and greenhouse trials with 6404 markers covering the whole genome, we detected 17quantitative trait locus(QTLs) on 11 chromosomes for IT associated with seedling resistance and 15 QTLs on seven chromosomes for IT, final disease severityor AUDPC associated with adult-plant resistance. Four stable QTLs detected on four chromosomes, which explained 9.99%–23.30% of the phenotypic variation, were simultaneously associated with seedling and adult-plant resistance. Integrating a linkage map of stripe-rust resistance in wheat, 29 QTLs overlapped with previously reported genes or QTLs, while two and oneQTLs conferring seedling and adult-plant resistancerespectively were mapped distantly from previously reported stripe rust resistance genes or QTLs and may be novel resistantloci. Conclusions:Our results provided an integrated view of stripe rust resistance resources in a Chinese wheat landrace diversity panel from the southern autumn-sown spring wheat zone.The identified resistant accessions and resistance loci will be useful in the ongoing effort to develop new wheat cultivars with strong resistance to stripe rust.
