Common Name

European pear, P. communis L., also an economically important species that is widely cultivated in Western countries, has distinct phenotypic and fruit quality characteristics that differ from those of Asian pear, including fruit shape, taste, lignin content, and aroma.

A draft genome sequence of the European pear ‘Bartlett’ version 1.0 was assembled and released using next-generation sequencing (NGS) technology (Roche454). Recently, an updated version of the European pear genome using a double-haploid ‘Bartlett’ cultivar was published. The quality and completeness of the European pear draft genome, designated BartlettDHv2.0, were greatly enhanced by integrating multiple technologies. In this updated draft genome, a total of 496.9 Mb sequences were assembled, and 445.1 Mb were anchored and oriented across all 17 chromosomes of the pear genome using both Hi-C data and a high-density genetic map.

Here, we provide only the BartlettDHv2.0 version of the Bartlett.
