Population structure of 38 <i>Physalis</i> accessions and two tomato lines using STRUCTURE software and 122 markers.

<p>The coefficients of estimated ancestry per accession in each cluster were represented by an individual bar, where each color refers to a distinct cluster. The name of the accession is below the bar.</p

Distribution of Nei's genetic distance values.

<p>The genetic distance was obtained from pair wise comparisons of 38 accessions of <i>Physalis</i> and 23 accessions of <i>P</i>. <i>philadelphica</i> with molecular marker data using the software NTSYSpc 2.11a.</p

Dendrogram of 38 <i>Physalis</i> accessions based on all marker data (A) and <i>P. peruviana</i> SSR marker data (B).

<p>The dendrogram was generated from Nei’s genetic distance matrix by UPGMA in NTSYSpc 2.11a. Tomato lines OH88119 and PI435238 were used as out-group controls.</p

Information for 38 accessions of the genus <i>Physalis</i> and two tomato lines used in this study.

<p>The information for all except the tomato line OH88119 were obtained from the website of Northeast Regional PI Station at Geneva, New York, USA (<a href="http://www.ars-grin.gov" target="_blank">http://www.ars-grin.gov</a>).</p

Number of polymorphic markers and alleles amplified from 38 <i>Physalis</i> accessions and 25 <i>P. philadelphica</i> accessions.

<p>The accessions with ambiguous species information were excluded from <i>P. philadelphica</i> cluster for calculation.</p
