Abstract
Malus niedzwetzkyana (MN) is the mother of Rosybloom hybrids, ornamental crabapples with red and purple flowers. We present a high-quality chromosome-scale genome for MN with a size of 672.64 Mb, anchored to 17 chromosomes and with a high BUSCO completeness score of 98.6%, reaching the 'gold standard' level. Moreover, our assembly has captured 28 telomeres. A total of 43,813 protein-coding genes was annotated in the MN genome. The assembled high quality provides a valuable opportunity to enhance our understanding of the genetic basis of flower colour and other ornamental traits in crabapples, thereby advancing the field of genetics and breeding.
期刊介绍：
Scientific Data is an open-access journal focused on data, publishing descriptions of research datasets and articles on data sharing across natural sciences, medicine, engineering, and social sciences. Its goal is to enhance the sharing and reuse of scientific data, encourage broader data sharing, and acknowledge those who share their data.
The journal primarily publishes Data Descriptors, which offer detailed descriptions of research datasets, including data collection methods and technical analyses validating data quality. These descriptors aim to facilitate data reuse rather than testing hypotheses or presenting new interpretations, methods, or in-depth analyses.
