For selection in Chinese breeding, 628 modern Chinese cultivars and 177 Chinese landraces were genotyped; TaNPF7.6-A1mod frequency was compared across periods before 1980, 1981–1990, 1991–2000, 2001–2010, and 2011–2020. The reported frequency rose from 22.22% before 1980 to 81.05% in 2011–2020 among the modern Chinese cultivars.",

  "searched": "Read the primary Nature Communications article’s geographical-distribution results, breeding-selection analysis, figure text, and methods. Checked the geographic database, accession denominators, landrace/cultivar composition, jurisdiction, and time bins. The global distribution analysis used 1,007 Watkins/Worldwide Wheat G2B accessions (188 modern cultivars and 819 A.E. Watkins landraces); the Chinese breeding-frequency analysis separately genotyped 628 modern cultivars and 177 landraces and compared periods from before 1980 through 2011–2020."
