Mapping QTLs for Leaf Wax Content in Wheat.

The objective of this study was to identify quantitative trait loci (QTL) associated with leaf waxes in wheat. A RIL population derived from a cross of Halberd and Karl 92 was grown in the greenhouse and field. Plants were grown in the greenhouse at 25C/ 20C day/night temperatures respectively. Leaf wax was collected at 10 DAP from the flag leaf. Flag leaf temperature and leaf width was measured in the greenhouse. The RIL population was evaluated for yield and yield components.  140 SSR markers were polymorphic between the parent lines. Preliminary QTL analysis identified 2 QTL associated with leaf wax on chromosome 2B and 6D.
