Technical Abstract: In the United States, cool-season grain legumes, including chickpeas, are integral components of cereal-based cropping systems in the Pacific Northwest and the Upper Midwest. The addition of a pulse crop helps break disease and weed cycles and adds nitrogen and organic matter to the soil. In this project, we are working to characterize the USDA Chickpea Core Collection as whole seed and as flour. As a start, using GBS, we genotyped a USDA kabuli mini-core collection of 88 accessions, discovering 174,040 variants. Using the software TASSEL to identify polymorphisms, 47,733 SNPs were identified using no-missing data criteria. The SNP numbers per chromosome were (1) 6296, (2) 4483, (3) 4330, (4) 9258, (5) 4471, (6) 6407, (7) 5917 and (8) 1571. Further genotyping is underway on the remaining 300 lines from the USDA chickpea core collection. We plan to use this resource for GWAS of end-use characteristics. Seed of the kabuli mini-core is available from USDA GRIN Global (https://npgsweb.ars-grin.gov/gringlobal/search.aspx) and the SNP data is available on the CSFL database (https://www.coolseasonfoodlegume.org/).
