Single-nucleotide polymorphism matrices for parental lines of a large diversity hybrid panel of wheat (Triticum aestivum L.)
Heterosis, the superior performance of hybrids over their parents, has been exploited systematically in crop breeding and  is considered a crucial asset for addressing global food demands. To investigate the genetic basis of midparent heterosis in hybrid  populations derived from diverse parental lines, a large hybrid dataset comprising 5,234 single crosses produced from 588 parental lines  were used to mapping the heterotic QTL.
