SSR sample data for a set of potato accessions


datasets

Gene banks increasingly use molecular markers for routine
characterization of plant collections and farmer managed diversity. The
gene bank of the International Potato Center presently uses a
micro-satellite marker kit to produce molecular profiles for potato
accessions. We have been searching for a compact graphical representation
that shows both molecular diversity and accession characteristics - thus
permitting biologists and collection curators to have a simple way to
interpret molecular data. Inspired by the ancient Andean data recording
system we devised a graph that allows for standardized representation while
leaving room for updates of the marker kit and the collection of
accessions. The graph has been used in several catalogs of potatoes.

potato.quipu function

Tabular format. The records represent unique SSR marker weights in base pairs as obtained
   for a set of three accessions. The combination of the first three columns is unique. The fourth
   column map_location is used for assigning markers to chromosomes or linkage groups.
<ul>
<li>"acccession_id" Accession ID
 </li>
<li>"marker" Marker name
 </li>
<li>"marker_size" Marker size
 </li>
<li>"map_location" Genetic ap location; usually Roman numbers for chromosomes or linkage group.
</li>
</ul>
