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, … WebOne key prediction is that genetic constraints should bias the early stages of species divergence along “genetic lines of least resistance” defined by the genetic (co)variance matrix, G. This bias is expected to erode over time as species means and G matrices diverge, allowing phenotypes to evolve away from the major axis of variation. gateway area.com https://designbybob.com

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. WebNov 27, 2011 · To asses G-matrix divergence between populations we calculated the angle between g max for matrices from different populations, where g max is the direction of maximum genetic variance, that is, the first principal component of the G-matrix, also known as the “genetic line of least resistance” (Schluter 1996). The angle between two ...
