Long-term persistence of crop alleles in weedy populations of wild radish (Raphanus raphanistrum).
*Hybridization allows transgenes and other crop alleles to spread to wild/weedy populations of related taxa. Researchers have debated whether such alleles will persist because low hybrid fitness and linkage to domestication traits could severely impede introgression. *To examine variation in the fates of three unlinked crop alleles, we monitored four experimental, self-seeding, hybrid populatio...
متن کاملPollinator preferences and the persistence of crop genes in wild radish populations (Raphanus raphanistrum, Brassicaceae).
Crop-weed hybridization can potentially influence the evolutionary ecology of wild populations. Many crops are known to hybridize with wild relatives, but few studies have looked at the long-term persistence of crop genes in the wild. This study investigated one factor in the hybridization process in radish: differential pollinator visitation to wild radish (Raphanus raphanistrum) vs. crop-wild...
متن کاملInvestigation of MCPA (4-Chloro-2-ethylphenoxyacetate) resistance in wild radish (Raphanus raphanistrum L.).
The phenoxy herbicides (e.g., 2,4-D and MCPA) are used widely in agriculture for the selective control of broadleaf weeds. In Western Australia, the reliance on phenoxy herbicides has resulted in the widespread evolution of phenoxy resistance in wild radish (Raphanus raphanistrum) populations. In this research the inheritance and mechanism of MCPA resistance in wild radish were determined. Foll...
متن کاملArtificial selection on anther exsertion in wild radish, Raphanus raphanistrum
To study the genetic architecture of anther exsertion, a trait under stabilizing selection in wild radish, artificial selection on anther exsertion was applied for 11 generations. Two replicate lines each of increased and decreased exsertion plus two randomly-mated controls were included. Full pedigree information is available from generation five. To estimate correlated responses to selection,...
متن کاملIdeal desiccation periods of Urochloa ruziziensis for a no-till sunflower crop
> Sowing crops following cover crops on forage may cause injuries andproductivity reduction, due reasons as allelopathy or glyphosate residues. Theobjective of this study was to evaluate the influence of differing periods betweencover crop (Urochloa ruziziensis) desiccation with glyphosate and sunflower(Aguará 4) sowing in a no-tillage system on crop development and productivity.Two assays were...
