Application of Molecular Tools for Wheat Quality Improvement: Indian Scenario

ICAR-ACIAR Workshop on Molecular Marker Assisted Breeding In Wheat, October 12, 2007


Wheat Grain Quality1. GPC & micronutrients (Fe, Zn)

- Nutritional quality

2. Pre-harvest Sprouting (PHS)- Activates hydrolyzing enzymes- Endosperm constituents are broken down- Decreased volume & poor crumb of bread- Lowers quality of grain for bread/feed and seed

3. GW- Aesthetic, market & industrial quality (flour recovery)


Wheat Grain Quality4. GPC, GW, sedimentation value, kernel

hardness, amylose content- Bread, biscuit, chapati and noodle quality

5. HMW-GS and LMW-GS- Flour processing properties/dough quality such as viscoelasticity & extensibility

6. Phytic acid- Reduces absorption of Fe and Zn

Applications of Molecular Markers

- Preparation of genetic maps- QTL analysis- High density mapping- Validation of linked markers- Molecular marker assisted selection


RIL Populations Used

- RIL pop for GPC (HD2329 × PH132)- RIL pop for PHST (WL711× SPR8198)- RIL pop for GW (CS × Rye Selection111)- RIL population for GH (K65 × Lerma Rojo)

Linked Markers and Their Validation

CSSU

Strategy for MAB• Three step selection during backcrossing

- Foreground selection for alleles for donor-parent markers flanking the QTL

- Background selection for the recipient-parent-alleles on loci of individual chromosome carrying the QTL

- Background selection for the recipient-parent-alleles for the whole-genome
