Abstract: The Kenyan wheat (Triticum aestivum L.) ?Kenya Kongoni ?exhibits high levels of adult plant resistance (APR) to leaf rust (LR) and yellow
rust (YR). We determined the genomic regions associated with LR and YR resistance in a population of 148 recombinant inbred lines generated
from a cross between ? Avocet-YrA ?and Kenya Kongoni. Field experi-ments to characterize APR to LR and YR were conducted in four and
two Mexican or Uruguayan environments, respectively. A linkage map was constructed with 438 diversity arrays technology and 16 simple-
sequence repeat markers by JoinMap 4.1 software. Genetic analyses showed that resistance to both rusts was determined by four to five
APR genes, including Lr46/Yr29 and Sr2/Lr27/Yr30 . Quantitative trait loci (QTL) analysis indicated that pleiotropic APR loci QYLr.cim-1BL
corresponding to Lr46/Yr29 and QYLr.cim-7BL that is a putative novel QTL accounted for 5 to 57% and 12 to 35% of the phenotypic variation
for resistance to LR and YR, respectively. These loci, in combination with another three LR QTL and two YR QTL, respectively, conferred
high levels of resistance to both LR and YR in wheat under Mexican and Uruguayan environments. Among ot her detected QTL, QLr.cim-1DS,
QLr.cim-2BL, and QYLr.icm-7BL may be new loci for APR to both rusts in common wheat. |

Abstract: To identify the production and consumption pathways and temporal dynamics of N2O emitted from soil, this study uses 15N-labelled substrate-N to quantify the underlying gross N transformation rates using the Ntrace analysis tool and link them to N-emissions. In three experiments twelve soil cores each were incubated in a lab incubation system to measure gaseous emissions, while parallel incubations under the same conditions were set up for destructive soil sampling at 7 time points. Using the triple labelling technique (applying NH4NO3 with either the NH4+-N or the NO3?-N, or both being 15N labelled), this study investigated the effects of 55, 70 and 85% water filled pore space (deemed to promote nitrification, both nitrification and denitrification, and denitrification, respectively) in a clay soil on gaseous N emissions and investigates the source and processes leading to N2O emissions. To assess the utilisation of applied NO3? vs. nitrified NO3? from applied NH4+, the 15N tracing tool Ntrace was used to quantify the rates of immobilisation of NO3? and NH4+, oxidation of NH4+, mineralisation of organic N and subsequent nitrification by the analysis of the 15N in the soil. Gross transformation rates were calculated, indicating the relative importance of added NO3? and NO3? derived from nitrified added NH4+. Results show an important contribution of heterotrophic nitrification (organic N oxidation to NO3?) which was highest at the 55% water filled pore space (WFPS), decreasing in its contribution to N-transformation processes with increasing WFPS, while nitrification (NH4+ oxidation to NO3?) was contributing the most at 70% WFPS. The contribution of denitrification increased with increasing WFPS, but only became dominant at 85% WFPS. While denitrification still showed to be most important at high and nitrification at lower WFPS, the actual % WFPS values were not as expected and highlight the fact that WFPS is a contributor, but not the sole/most important parameter determining the type of N-transformation processes taking place.
