Wheat Grain Hardness: Genetics XpinA XpinB XGsp T. aestivum 5DS T. monococcum 5Am • Softness is dominant • Genes at the Halocus are responsible for the • production of Friabilin associated with softness XNor Ha • Friabilin is a mixture of Puroindolin A (pinA) and B (pinB) XpinA, XpinB,XGsp • New allelic variants in grain texture genes expand the range of variation in hardness XNor, Xmwg920 Xmwg920 10 cM 10 cM Xtam53 XDor5 Xpsr326 Xabg705 Xtam53 XDor5 Xabg395 Hardness is mainly controlled by the Ha locus on 5DS in bread wheat Xcdo749 Xwg541
