UPGMA dendrogram of the Zengcheng (ZC) wild rice population based on phenotypic and genotypic data.

<p>A and B show dendrograms based on phenotypic and genotypic data, respectively. Red dots show accessions selected for the core collection with high genetic distance and green squares denote accessions selected for the core collection with a gradual increase in genetic distance (from low to high). Numbers in vertical rows represent accessions selected as core collection. Numbers on the lower side of A represent genetic relevance and numbers on the upper side of B represent genetic distance.
