A maximum of 11 stripe rust resistance loci (QYr
QTLs having stripe rust opposition
lrdc-2A, QYr.lrdc-2B.1, QYr.lrdc-2B.2, QYr.lrdc-2B.step three, QYr.lrdc-2B.cuatro, QYr.lrdc-2D, QYr.lrdc-3B, QYr.lrdc-5A, QYr.lrdc-5B, QYr.lrdc-5D and QYr.lrdc-7D), have been identified inside studies (Fig. 3; Desk 3). Such QTLs was in fact mapped so you can chromosomes 2A, 2B, 2D, 3B, 5A, 5B, 5D and you may 7D, correspondingly (Fig. step 3 and you can Table step three). Between these types of, QYr.lrdc-2A was the only biggest impact QTL thought of throughout environment. QYr.lrdc-2A are recognized in the 218.1–240.six cM interval towards the LOD score ranged regarding 8.02 into the Lethbridge 2016 in order to in Lethbridge 2017 plus in the fresh shared analysis utilising the pooled study (Fig. 4 and Table step 3). The latest proportion of phenotypic type told me through this QTL ranged away from 14% in the Lethbridge 2016 so you can 31% in the Lethbridge 2019 and 33% with the pooled studies.

Fig. cuatro The brand new linkage chart away from chromosome 2A in addition to the logarithm of odds (LOD) traces having biggest stripe rust opposition decimal trait locus (QTL) QYr.lrdc-2A seen during the each one of the four trial surroundings and you will pooled study. Remaining panel: linkage map regarding chromosome 2A to your QTL QYr.lrdc-2A phase emphasized on chromosome in lime along with while the delimiting markers conveyed inside red colour . Positions (cM) regarding indicators get to the left of linkage class, in addition to es are shown to the right. Proper panel: LOD shape of biggest stripe corrosion opposition QTL QYr.lrdc-2A seen using chemical interval mapping from inside the each of the four demo environments and you may pooled investigation. The fresh vertical straight line is short for the single LOD significance threshold out of step 3.dos to have pooled data. LET16, LET17 and LET20: Lethbridge community samples inside the 2016, 2017 and 2020, respectively; CRE16 and you can CRE20: Creston profession products during the 2016 and you can 2020, correspondingly
Fig. cuatro The linkage chart out-of chromosome 2A plus the logarithm off opportunity (LOD) contours having significant stripe rust opposition quantitative feature locus (QTL) QYr.lrdc-2A thought inside each of the five trial surroundings and you may pooled studies. Left committee: linkage chart out of chromosome 2A with the QTL QYr.lrdc-2A section showcased towards chromosome during the tangerine the color while the delimiting markers shown inside reddish the colour. Ranking (cM) out-of markers get to the left of linkage group, together with parece are provided off to the right. Best panel: LOD curves out-of biggest stripe rust resistance QTL QYr.lrdc-2A identified having fun with ingredient interval mapping in the each of the five demo surroundings and you can pooled studies. The fresh new vertical straight line signifies new single LOD value endurance away from 3.dos to own pooled research. LET16, LET17 and LET20: Lethbridge occupation examples into the 2016, 2017 and 2020, respectively; CRE16 and you will CRE20: Creston community products for the 2016 and you can 2020, correspondingly
The second most secure QTL, QYr.lrdc-5A, was thought in the four regarding four surroundings and you will taken into account 5% to help you eight% phenotypic type during the private surroundings and you can seven% in the mutual investigation with the pooled analysis. The QYr.lrdc-5A try mapped inside 57.1–65.eight cM period that have an effective LOD get anywhere between step 3.07 into the Lethbridge 2016 so you’re able to 5.61 within the Lethbridge 2017 and you may 5.99 from the mutual study making use of the pooled data. The fresh QYr.lrdc-7D try identified in 2 environments, having a LOD score of 5.0 and you can six.0, and informed me phenotypic version as much as 5 and you can 6%, correspondingly. ‘AAC Proclaim’ shared resistance alleles in the QYr.lrdc-5A and you may QYr.lrdc-7D (Dining table step three).
Remaining QTLs were understood in book environments, that have otherwise instead of pooled study. not, chromosome 2B harboured five QTLs namely QYr.lrdc-2B.1, QYr.lrdc-2B.dos, QYr.lrdc-2B.3 and you will QYr.lrdc-2B.4, anywhere between 103.nine and you may 189.step 3 cM, towards the possibility that they depict just one locus. Such loci explained 5%, 7%, 6% and 8% off phenotypic type, correspondingly. ‘AAC Innova’ discussed stripe rust alleles after all the brand new four loci (Desk 3).
