Genetic relatedness of previously Plant-Variety-Protected commercial maize inbreds
The emergence of high-throughput, high-density genotyping methods combined with increasingly powerful computing systems has created opportunities to further discover and exploit the genes controlling agronomic performance in elite maize breeding populations. Understanding the genetic basis of population structure in an elite set of materials is an essential step in this genetic discovery proces...
متن کاملMolecular Characterization of Maize Inbreds with Expired U.S. Plant Variety Protection
Maize inbred lines with expired Plant Variety Protection Act (PVPA) certifi cates are publicly available and potentially represent a new germplasm resource for many public and private breeding programs. However, accurate pedigree and genetic background information for ex-PVPA maize inbreds is necessary if they are to be effectively utilized in breeding efforts. We have used single nucleotide po...
متن کاملGene mapping with recombinant inbreds in maize.
Recombinant inbred lines of maize have been developed for the rapid mapping of molecular probes to chromosomal location. Two recombinant inbred families have been constructed from F2 populations of T232 X CM37 and CO159 X Tx303. A genetic map based largely on isozymes and restriction fragment length polymorphisms has been produced that covers virtually the entire maize genome. In order to map a...
متن کاملHeritable Epigenetic Variation among Maize Inbreds
Epigenetic variation describes heritable differences that are not attributable to changes in DNA sequence. There is the potential for pure epigenetic variation that occurs in the absence of any genetic change or for more complex situations that involve both genetic and epigenetic differences. Methylation of cytosine residues provides one mechanism for the inheritance of epigenetic information. ...
