    1. About Sorghum

    • Q: What's the difference between the term Sorghum Accession and Sorghum line?
      A: Sorghum Accession is the official identification assigned by the national or province crops variety examination and approval committee, sorghum line is a strain with homozygous genotype.

    • Q: What's the difference between the term Sorghum Line and Sorghum Race?
      A: Sorghum race is classified five basic races based on morphological study of sorghum grain and ten hybrid races that combine characteristics of any two basic races. Each sorghum race is consisted of sorghum lines.

    • Q: What's the difference between the term Improved Inbred and Improved Variety?
      A: Improved Inbred is sorghum line bred by hybridization, including male sterile line, maintenance line and restore line in general, improved variety is hybrid crossed by restore line and male sterile line.

    • Q: What's the difference between the term Landrace and Inbred?
      A: Landrace is sorghum line without pedigree planted by farmer for long time. Inbred is sorghum line bred by hybridization with pedigree.

    2. About the dataset

    • Q: How may sorghum accessions does SorGSD contains?
      A: It contains 48 accessions. 46 accessions are individual races of Sorghum Bicolor: 20 improved inbred; 19 landraces; 7 wild and weedy races. The other 2 accessions are from its close relative Sorghum propinquum.

    • Q: Does SorGSD have InDels?
      A: Currently, SorGSD has sorghum SNP data only. We will add InDels data in the new release.

    • Q: Does SorGSD contain sorghum genome structural variation data?
      A: Currently, SorGSD does not contain structural variation data. We plan to add them in the new release.

    • Q: Can I download all the SNP data for local analysis?
      A: All the SNP data as well as the short reads for the 44 accessions (SRA files) and FASTQ file for the 4 accessions can be downloaded.

    • Q: How many disk space should I have to store the SNP data files?
      A: The SNP data (VCF files) are about 11 GB, the 44 SRA files are 471 GB, and the FASTQ files are about 26 GB.

    • Q: Could I download the data to a Windows system?
      A: Please talk to your colleague to download the data under a Linux system. It is not practical to use Windows to store and analyze the data.
