Rapid advances in cereal biotechnology have emerged as a convincing
alternative to the conventional breeding techniques,
which are often complicated and cumbersome, hampering the much-desired
increase in grain quality and quantity. Wheat is characterized by a
large genome size (~17000 Mb) thus making the improvement process by
any method genetically challenging. Crop biotechnology has emerged as
one of the latest tools of agricultural research in concert with traditional
plant breeding. Subsequent to the change in the global food policy,
in the last few decades, emphasis in wheat improvement have shifted
from raising the yield potential to quality characteristics, resistance
to biotic stresses and tolerance to abiotic stresses to meet the future
demands associated with global weather changes. Additionally, the surplus
grain situation has
also forced a shift in perspective from quantity production to quality
and value addition to enhance the overall exportability of wheat. With
the advent of new strategies for gene transfer, it is now feasible that
wheat too, in its various genetically modified forms, will soon mark
its presence in the world market. The present endeavor thus envisages
to evolve strategies for efficient gene delivery in Indian wheat varieties
of commercial significance, and to develop transgenics capable of withstanding
the changing global climatic changes and meet the ever-increasing demand
both quantitatively as well as qualitatively. A three-pronged approach
is thus envisioned to meet the futuristic challenges in Wheat Biotechnology
which are as follows:
• Genomics and Gene Discovery
• Regeneration and Transgenic Production
• Manipulation of Agronomic Traits for Abiotic Stress Tolerance
