Table 2 . Chromosomal location and size of the different phenotypic QTL.
| Traits | Chromosome | Size (kb) | Start Position (pb) | End Position (pb) | LOD Threshold | LOD Score |
|---|---|---|---|---|---|---|
| Rmax | XIV | 37.50 | 664875 | 702375 | 3.64 | 4.76 |
| Nass | XIV | 37.50 | 664875 | 702375 | 3.73 | 3.91 |
| Fd | II | 69.74 | 246162 | 315903 | 3.05 | 3.27 |
| R50 | II | 69.74 | 246162 | 315903 | 3.74 | 3.11 |
| Succinate | II | 43.58 | 227328 | 270903 | 3.31 | 3.12 |
| R70 | II | 60.00 | 263403 | 323403 | 3.75 | 4.1 |
| Cp | XVI | 37.16 | 25617 | 62772 | 3.24 | 3.27 |
| Succinate | XIV | 60.00 | 447375 | 507375 | 3.31 | 4.01 |
The gray colors in the table indicate QTL that are overlapping. The first group of overlapping QTL, which is located on chromosome XIV, involved the maximum fermentation rate variation (Rmax) and nitrogen assimilation (Nass). The other group, which is localized on chromosome II, involves four traits as the succinate production, the fermentation duration, and the fermentation rate at 50% and 70% of sugar consumption. Two QTL mentioned (R50 and succinate on chromosome II) have a maximum LOD score just below the threshold but are conserved because they overlap with Fd and R70 QTL on chromosome II.
