    • Recent advances in genomics, transcriptomics, proteomics and metabolomics are leading to identification of thousands of genes governing response to abiotic / biotic stresses, end-use quality and nutritional quality in crops. It is essential to integrate this information in crop breeding to develop next generation crop varieties.

Mapping quality traits in durum wheat & development of functional markers for MAS:

 

    • More recently, the demand of good quality industrial products is also growing because of change in life style and food habit of the urban population in India. Therefore, it is essential to improve its end-use quality so as to meet the international standards. An intraspecific genetic linkage map has been developed from a durum wheat RIL population obtained from a cross of cultivar PDW 233 and landrace Bhalegaon 4. The map was successfully used to locate the genes/QTLs for test weight, thousand kernel weight, gluten strength, grain protein content and carotenoids content in Indian durum wheat. A Psy-A1 (phytoene synthase) specific marker has been developed for carotenoids content and also validated in diverse genetic backgrounds, demonstrating its utility in the improvement of the trait in durum wheat.

 

GA-sensitive dwarfing genes and crop establishment traits in durum wheat

 

    • The shorter coleoptile of semi-dwarf wheat do not affect seedling establishment under optimum conditions of moisture and fertilizers, hence produce optimum yields. However, under moisture stress conditions short coleoptiles reduce yield through poor seedling establishments in gibberellic acid (GA) -insensitive semi-dwarf wheat. In contrast, semi-dwarf wheat with GA-sensitive dwarfing genes are known to be tolerant to moisture stress conditions owing to their longer coleoptile, better emergence and seedling vigour. Therefore, GA-sensitive dwarfing genes with longer coleoptile may provide a useful alternative to widely used GA-insensitive dwarfing genes under water stress conditions. In view of the above, it is important to generate genetic and genomic resources such as molecular markers linked to GA-sensitive dwarfing genes and QTL for longer coleoptile which would facilitate development of durum wheat genotypes better adapted to semiarid conditions in a short period of time using MAS.

 

Breeding for high yielding, disease resistant wheat varieties with better quality attributes

 

    • The Institute is one of the centers of ICAR, New Delhi for implementing All India Coordinated Wheat and Barley Improvement Project. Wheat research at ARI is aimed at developing high yielding, disease resistant wheat varieties particularly of durum wheat for India in general and peninsular zone in particular. I have contributed towards successful development and release of two bread wheat (MACS 6222 & MACS 6478) and one dicoccum wheat variety (MACS 2971) for Peninsular India.

 

Development of markers for resistance to biotic stresses

 

    • Among several constrains towards realizing the potential yield in crops, losses occurred due to fungal pathogens are enormous ranging from 15 to 70% under favourable environment. Therefore, deployment of resistant cultivars remains the most effective strategy for management of the disease. Molecular characterization of disease resistance genes in crops will help to develop functional markers for marker-assisted breeding for disease resistance in wheat.
