Joint linkage and association analysis identifies genomic regions and candidate genes for yield-related traits in wheat.

ABSTRACT:

Key message

Twenty-six QTLs associated with yield-related traits in wheat were identified through joint linkage and association analysis, with TraesCS5A03G0002500 being selected as a candidate gene for QGl.caas-5A.1. As a major staple crop worldwide, continuously increasing wheat yield is crucial for ensuring food security. Wheat yield is influenced by multiple traits, and elucidating the genetic basis of yield-related traits lays a foundation for future gene cloning and molecular mechanism studies. In this study, a recombinant inbred line (RIL) population derived from 292 lines of Hengguan 35/Zhoumai 18 was genotyped with the Affymetrix wheat 660 K SNP array. Combined with the phenotype of the RIL population in 13 environments, linkage analysis of six yield-related traits includin
