Pyrus ussuriensis x communis_Zhongai 1

'Zhongai 1' [(Pyrus ussuriensis × communis) × spp.] is an excellent pear dwarfing rootstock common in China. It is dwarf itself and has high dwarfing efficiency on most of main Pyrus cultivated species when used as inter-stock.

Here we describe the draft genome sequences of 'Zhongai 1' which was assembled using PacBio long reads, Illumina short reads and Hi-C technology. We estimated the genome size is approximately 511.33 Mb by K-mer analysis and obtained a final genome of 510.59 Mb with a contig N50 size of 1.28 Mb. Next, 506.31 Mb (99.16%) of contigs were clustered into 17 chromosomes with a scaffold N50 size of 23.45 Mb. We further predicted 309.86 Mb (60.68%) of repetitive sequences and 43,120 protein-coding genes.
