Figure 4From: Identification and independent validation of a stable yield and thousand grain weight QTL on chromosome 6A of hexaploid wheat (Triticum aestivum L.)Effect of 6A introgression on grain morphometric parameters. Percentage increase conferred by the Rialto introgression in the 6A BC2 NILs (2010–2012) and BC4 NILs (2013). Significant differences are represented by * (P <0.05), ** (P <0.01) and *** (P <0.001).Back to article page
