“…It cosegregates with the leaf tip necrosis gene Ltn2 (Rosewarne et al, 2006), Pm39 for APR to powdery mildew (Lillemo et al, 2008), and Sr58 for APR to stem rust (Singh et al, 2013). Lr46 / Yr29 reportedly confers weaker levels of resistance to leaf rust and powdery mildew than Lr34/Yr18 (Lagudah, 2011) but displayed larger effects in the Avocet/Pastor and Avocet/Francolin#1 genetic backgrounds (Rosewarne et al, 2012; Lan et al, 2014). However, this gene contributed a significant negative effect when combined with Lr34/Yr18 in Avocet/Saar on the basis of a simple additive model of analysis (Lillemo et al, 2008).…”

Leaf rust and powdery mildew, caused by Puccinia triticina and Blumeria graminis f. sp. tritici, respectively, are widespread fungal diseases of wheat (Triticum aestivum L.). Development of cultivars with durable resistance is crucially important for global wheat production. This paper reviews the progress of genetic study and application of adult plant resistance (APR) to wheat leaf rust and powdery mildew. Eighty leaf rust and 119 powdery mildew APR quantitative trait loci (QTL) have been reported on 16 and 21 chromosomes, respectively, in over 50 publications during the last 15 yr. More important, we found 11 loci located on chromosomes 1BS, 1BL, 2AL, 2BS (2), 2DL, 4DL, 5BL, 6AL, 7BL, and 7DS showing pleiotropic effects on resistance to leaf rust, stripe rust, and powdery mildew. Among these, QTL on chromosomes 1BL, 4DL, and 7DS also correlate with leaf tip necrosis. Fine mapping and cloning of these QTL will be achieved with the advent of cheaper high‐throughput genotyping technologies. Germplasm carrying these potential resistance genes will be useful for developing cultivars with durable multidisease resistance. In addition to its non‐NBS–LRR (nucleotide binding site–leucine rich repeat) structure, the senescence‐like processes induced by Lr34 could be the reason for durability of resistance; however, more information is needed for a full understanding of the molecular mechanism related to durability. Adult plant resistance genes have been used by CIMMYT for more than 30 yr and have also been transferred to many Chinese wheat varieties through shuttle breeding.

“…Although the locus in 'Lumai 21' conferred resistance to both stripe rust and leaf rust, there was no significant effect in reducing the severity of powdery mildew (Lan et al 2010a, Liu et al 2014. We tested 'Lumai 21' and 'Jingshuang 16' using the SNP marker csSNP856 that was cosegregating with Lr67/Yr46 locus (Herrera-Foessel et al 2014) and did not find any polymorphisms between two parents indicating that QYr.caas-4DL.2 is different from Yr46. The effects of the potential pleiotropic APR QTL might therefore be influenced by different genetic background.…”

“…Many APR genes in wheat are associated with molecular markers, such as Yr16 on chromosome 2DL (Devos et al 1993 (Ren et al 2012a) and Yr54 on 2DL (Basnet et al 2013). Among them, the loci Yr18/Lr34, Yr29/Lr46 and Yr46/Lr67, initially identified to confer resistance to stripe rust and leaf rust, also pro-vide partial resistances to powdery mildew and stem rust, with additional designations as Pm38/Sr57, Pm39/Sr58 and Pm46/ Sr55, respectively (Lillemo et al 2008, Herrera-Foessel et al 2014. These genes confer low to moderate levels of resistance to rusts when present alone, but in combinations with other slow-rusting genes, high levels of resistance can be achieved (Singh et al 2000a, Herrera-Foessel et al 2011.…”

Stripe rust, caused by Puccinia striiformis f. sp. tritici, is a devastating fungal disease in common wheat (Triticum aestivum L.) worldwide. Chinese wheat cultivars ‘Lumai 21’ and ‘Jingshuang 16’ show moderate levels of adult‐plant resistance (APR) to stripe rust in the field, and they showed a mean maximum disease severity (MDS) ranging from 24 to 56.7% and 26 to 59%, respectively, across different environments. The aim of this study was to identify quantitative trait loci (QTL) for resistance to stripe rust in an F3 population of 199 lines derived from ‘Lumai 21’ × ‘Jingshuang 16’. The F3 lines were evaluated for MDS in Qingshui, Gansu province, and Chengdu, Sichuan province, in the 2009–2010 and 2010–2011 cropping seasons. Five QTL for APR were detected on chromosomes 2B (2 QTL), 2DS, 4DL and 5DS based on mean MDS in each environment and averaged values from all three environments. These QTL were designated QYr.caas‐2BS.2, QYr.caas‐2BL.2, QYr.caas‐2DS.2, QYr.caas‐4DL.2 and QYr.caas‐5DS, respectively. QYr.caas‐2DS.2 and QYr.caas‐5DS were detected in all three environments, explaining 2.3–18.2% and 5.1–18.0% of the phenotypic variance, respectively. In addition, QYr.caas‐2BS.2 and QYr.caas‐2BL.2 colocated with QTL for powdery mildew resistance reported in a previous study. These APR genes and their linked molecular markers are potentially useful for improving stripe rust and powdery mildew resistances in wheat breeding.

“…In these alleys the susceptible 'Morocco' was planted. The 'Morocco' plants were inoculated with a suspension of uredospores (1 × 10 6 uredospores mL -1 ) of the MCJ/SP and MBJ/SP leaf rust races four times to generate the epiphyte following the standard CIMMYT methodology (Lan et al, 2014). Rust severity ratings were taken according to the modified Cobb scale (Peterson et al, 1948).…”

The adult plant resistance conferred by genes with an additive effect is an alternative to achieve durable resistance to leaf rust caused by the fungus Puccinia triticina in wheat (Triticum spp.) The objective of this study was to know the response to this disease in bread wheat genotypes that possess the partial resistance genes Lr34, Lr46, Lr67 and Lr68. The severity level of the disease was measured in 280 wheat genotypes in three locations. The presence or absence of partial resistance genes was determined by molecular markers for each gene in 245 wheat genotypes. The different combinations of adult plant genes resulted in the genotypes were classified into nine groups. In 77 of these genotypes, the markers were negative for these genes. The Lr34, Lr46, Lr67 and Lr68 genes were identified individually in 48, 48, 5, and 14 genotypes, respectively. The combination of two genes, Lr34+Lr46, Lr34+Lr68 and Lr46+Lr68, was determined in 18, 17, and 12 genotypes, respectively. Only in six genotypes the combination Lr34+Lr46+Lr68 was identified. The genotypes with the Lr34, Lr46, Lr67 and Lr68 genes in a unique form showed 21%, 24.8%, 21.9% and 21.8% of rust severity on average, respectively. An additive effect was observed in the combinations of two genes, and higher effect in the combinations that included the Lr34 gene since genotypes with this gene combination showed on average 11.4% of rust severity. The combination of three genes Lr34+Lr46+Lr68 provide greater protection in the genotypes with 9.7% of rust severity on average.
