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:
Nine lactating cows fed a total mixed ration (TMR) were assigned to three 3 × 3 Latin squares with 20-day periods to evaluate the effects
of access time to fresh forage (FF) on behaviour and dry matter intake rate (DMIR). Forage (Lolium multiflorum) was cut daily and
individually offered from 0800 h for 0 (T0), 4 (T4) or 8 (T8) hours of daily access, and a TMR was offered during the remaining time.
Treatments had no effect on the average proportion of time spent eating or ruminating. However, the distribution of behaviours
across time was different among treatments, with T4 and T8 cows spending a high proportion of the available time eating and
achieving a high DMIR only when they had access to TMR. Additional research is warranted to identify strategies that
increase the DMIR of TMR-fed cows when FF is progressively included in their diet. |
