Background In this study, we used phenotypic and genetic analysis to investigate Double
haploid (DH) lines derived from normal corn parents (HF1 and 11S6169). DH technology …

Gene expression differences between divergent lineages caused by modification of cis
regulatory elements are thought to be important in evolution. We assayed genome-wide cis …

Cost, time, linkage drag, and genetic drift work against the incorporation of potentially
valuable alleles from exotic or non-adapted germplasm into elite crop plants, particularly for …

High-density genotyping is extensively exploited in genome-wide association mapping
studies and genomic selection in maize. By contrast, linkage mapping studies were until …

Improvement in traits of agronomic importance is the top breeding priority of crop
improvement programs. Majority of these agronomic traits show complex quantitative …

The length of time needed for prebreeding in adapted× exotic maize (Zea mays L.) crosses
has deterred breeders from exploiting exotic germplasm. My objective in this study was to …

There is increasing evidence that epigenetic marks such as DNA methylation contribute to
phenotypic variation by regulating gene transcription, developmental plasticity, and …

In the cooler temperate regions of the world, maize (Zea mays L.) is primarily cultivated for
forage usage. In this study, we mapped and characterized quantitative trait loci (QTL) …

Crop plants were domesticated by prehistoric farmers through artificial selection to provide a
means of feeding the human population. This article discusses the developmental genetics …

Background Collections of nearly isogenic lines where each line carries a delimited portion
of a donor source genome into a common recipient genetic background are known as …
