Updated Pinus lambertiana high-density linkage maps

# Updated Pinus lambertiana high-density linkage maps [https://doi.org/10.5061/dryad.573n5tbdz](https://doi.org/10.5061/dryad.573n5tbdz) Give a brief summary of dataset contents, contextualized in experimental procedures and results. This dataset contains 2 excel files containing linkage maps for sugar pine (Pinus lambertiana). Distance is given in centimorgans (cM). Linkage groups are given as "L1, L2, ..L12". Linkage group IDs are randomly assigned and do not match in BC1 and BC2. Description of the data and file structure Sugar pine (Pinus lambertiana) is a five-needle pine of great economical and ecological importance in western North America. Genome-wide analyses in the species have been limited by the absence of a chromosome-scale reference genome. The genome of the species is one of the largest in any plant diploid species, with a size of 31 Gb, making assembly and annotation very challenging. Here we present high-density linkage maps that were used to help scaffolding a new chromosome-scale genome of sugar pine (assembly version 2.0, unpublished). Describe relationships between data files, missing data codes, other abbreviations used. Be as descriptive as possible. ## Sharing/Access information This is a section for linking to other ways to access the data, and for linking to sources the data is derived from, if any. Links to other publicly accessible locations of the data: * Weiss et al. 2020. The Plant Journal. http://doi.org/10.1111/tpj.14928 Data was derived from the following sources: * ## Code/Software This is an optional, freeform section for describing any code in your submission and the software used to run it. Describe any scripts, code, or notebooks (e.g., R, Python, Mathematica, MatLab) as well as the software versions (including loaded packages) that you used to run those files. If your repository contains more than one file whose relationship to other scripts is not obvious, provide information about the workflow that you used to run those scripts and notebooks.
