Biotechnology applications for wheat improvement at CIMMYT uri icon

abstract

  • Despite the tremendous advances made by plant breeders in increasing the global food production, there is still asignificant need for increased quantity and quality of food items in various regions of the world. Although this can be partially solvedby upgrading the storage and distribution networks, crop performance and yield potentials are constantly challenged by variousbiotic and abiotic stress factors. As additional tools to facilitate the global wheat breeding efforts at CIMMYT, we have used molecularmarkers for characterizing loci that confer adult plant resistance to leaf rust and yellow (stripe) rust, which are globally importantdiseases in wheat. We have also established a biotechnology laboratory that is charged with acquiring, validating and applyingmarkers for certain traits that are important to CIMMYT wheat breeders. Use of PCR based markers coupled with rapid DNAextraction procedures have enabled application of markers on a wide range of material. Genetic engineering procedures have alsobeen used to establish procedures as well as for experimenting with genes that confer resistance to various biotic and abiotic stressesin wheat
