Many plant species of great economic value (e.g., potato, wheat, cotton and sugarcane) are polyploids. Despite the essential roles autopolyploid plants in human activities, our genetic understanding these is still poor. Recent progress instrumentation biochemical manipulation has led to accumulation an incredible amount genomic data. In this study, we demonstrate for first time a successful analysis highly polyploid genome (sugarcane) by quantitative single-nucleotide polymorphism (SNP)...
Expressed sequence tags (ESTs) offer the opportunity to exploit single, low-copy, conserved motifs for development of simple repeats (SSRs). The authors have examined Sugarcane Sequence Tag database presence SSRs. To test utility EST-derived SSR markers, a total 342 EST–SSRs, which represent subset over 2005 SSR-containing sequences that were located in sugarcane EST database, could be designed from nonredundant SSR-positive ESTs possible use as potential genic markers. These EST–SSR markers...

Abstract Quantitative trait locus (QTL) mapping contributes to sugarcane ( Saccharum spp.) breeding programs by providing information about the genetic effects, positioning and number of QTLs. Combined with marker-assisted selection, it can help breeders reduce time required develop new varieties. We performed a QTL study for important agronomic traits in using composite interval method outcrossed species. A approach allowing 1:2:1 segregation ratio different ploidy levels SNP markers was...
Recent years have witnessed enormous growth in Unmanned Aircraft System (UAS) and sensor technology which made it possible to collect high spatial temporal resolutions data over the crops throughout growing season.
