QTL mapping of wheat plant architectural characteristics and their genetic relationship with seven QTLs conferring resistance to sheath blight.

ABSTRACT: Sheath blight is one of the most devastating wheat diseases worldwide. Breeding resistant cultivars is the most powerful strategy to defeat the disease. Plant resistance on "disease escape" works through modulation of morphological traits and shows sustainable resistance to disease. Plant architectural traits have been reported to play a significant role in disease response. Therefore, exploring the genetic relationship between plant architecture and disease resistance is of importance to the understanding of plant resistance via "disease escape". Using an F9 population of 266 RILs (Recombinant Inbred Lines) derived from the cross of Luke × AQ24788-83, we have generated a linkage map of 631 markers on 21 chromosomes. In this study, we present the QTL identification of fourteen plant archit
