WebThe Canada Western Red Spring wheat (Triticum aestivum L.) cultivars AAC Concord, AAC Prevail, CDC Hughes, Lillian, Glenlea, and elite line BW961 express a spectrum of resistance to leaf rust caused by Puccinia triticina Eriks. This study aimed to identify and map the leaf rust resistance of the cultivars using three doubled haploid populations, … WebWe quantified the genetic constraint from the G-matrix using the angle (θ) between the genetic lines of least resistance (g max) and the actual domestication trajectory (Z). g max is the eigenvector of G that accounts for the most variation, while Z is a vector of difference in trait means between teosinte and maize landrace.
