To possess SH, the consistent QTL qSH1–step 1 (named as qSH1–step 1
I used a blended data of the two populations to understand the effect of varying QTL combinations towards germination below cardio and you will anaerobic criteria in the 21 DAS
Rc222-SCR-14, qSH1–1Rc222-SCR-21 and qSH1–1Rc222-TAB-21) identified by a LOD score of 5.18 to 7.17 had an additive effect of 1.3% to 3.4% and could explain 13.5% to 18.5% of the phenotypic variation. A second position on chromosome 3, qSH3–2 (named as qSH3–2Rc222-SCR-fourteen and qSH3–2Rc222-SCR-21) that is different from the detected QTL from the other population for the same trait was identified by an LOD score of 3.78 to 4.87 and could explain 10.2% to 11.7% of the phenotypic variation (Additional file 1: Table S3, Additional file 1: Figure S3B).
Altogether, around three secure QTLs towards the chromosome 3, six, and seven getting Sur (Fig. 3) and one secure QTL into the chromosome step one to possess SH (More document step 1: Figure S3B) was recognized having fun with one another populations not as much as both evaluating conditions having 21 DAS, certainly that the QTLs into chromosome 6 and you will chromosome step 1 have perhaps not already been advertised before into traits into the best of all of our knowledge.
Under control conditions, a QTL for normally established seedlings as germination percentage was detected on chromosome 9 (qGER9-1Rc222-CON-21), which was contributed by susceptible parent NSIC Rc222 (Table 3). The SH QTL on chromosome 1 (qSH1-2Rc238-CON-21) was also detected in a different position in control conditions from the one detected under stress. This QTL was detected by a LOD score of and explained 21.9% of the phenotypic variation with an additive effect of 2.3% (Additional file 1: Table S3).
Every known QTLs informed me a whole phenotypic variation ranging from % in order to % getting Sur and 13.5% so you can 28.7% getting SH contained in this society.
Aftereffect of QTL Kinds
Three QTLs (qSUR3–step one, qSUR6–step 1 and you can qSUR7–1) that have a giant and you will secure feeling along the one or two populations had been recognized contained in this research. Contour 4 gift suggestions the brand new commission benefit of differing groups out-of QTLs across the populace imply both for immersed and you will handle standards. In balance requirements, the three QTLs did not show people extreme impact on germination plus the benefit of the QTL categories remained close to zero along the people mean while the shown from the Pairwise Mann-Whitney You-tests. Below AG conditions, but not, qSUR7–1 demonstrated the best effect on this new characteristic, followed closely by qSUR6–1 and you may qSUR3–1, correspondingly. It absolutely was also observed that contours having qSUR3–1 and you will qSUR6–step 1 got a notably large advantage over the latest traces with just among the many two QTLs. The QTL qSUR7–1, however, offered a premier virtue actually with no almost every other a couple QTLs. The consolidation which have qSUR6–step 1 enhanced the entire advantage, which was then improved regarding contours along with three QTLs combined, even when speaking of maybe not statistically extreme. The increase for the advantage of a QTL whenever along with the most other QTLs ways its ingredient character. Traces to the combination of qSUR7–1 and qSUR3–step one were not included in each other communities. Also, traces with no three QTLs had the low germination of all categories that has been below the populace mean.
