Wheat

IIWBR, PAU, CCSHAU-Hisar, UAS-D, IARI- Indore (5)

 


Short term objectives

 

  • Evaluation of wheat germplasm including diploids, tetraploids, bread wheat and synthetic hexaploids for identification of wheat accessions with high micronutrient density and  phytase levels  and low phytic acid content in Indian conditions.
  • Development of genetic stocks in high yielding backgrounds for higher micronutrient density and phytase levels and low phytic acid content.
  • Bioavailability studies to identify nutrient rich genotypes with higher bioavailable Fe and Zn. 

 

Medium term objectives

  • Transferring Gpc-b1 gene into high yielding back grounds of wheat with the objective to enhance micronutrient density and higher grain protein content.
  • Transferring Gpc-b1 gene into high yielding back grounds of wheat with the objective to enhance micronutrient density and higher grain protein content.
  • Molecular mapping and tagging of genes associated with higher concentration of Fe and Zn, and higher phytase levels followed by genetic studies and molecular breeding.
  • Allele mining of genes for identification of desired alleles and their utilization in  breeding 

Long term objective 

 

Development of high yielding wheat genotypes with higher content of Fe and Zn and their enhanced bioavailability for the improvement of nutritional quality
