Molecular breeding is the use of tools of biotechnology (DNA markers/genes) as a substitute for phenotypic selection and to accelerate the improvement of crop cultivars for desired traits. Molecular breeding involves the following steps to achieve targeted crop improvement..
- Development of mapping populations in target crops
- Identifying genes/QTLs for yield potential and stability
- Identifying high-yielding, stable genotypes (low G x E x M)
- Understanding of genetic networks for correlated traits
- Construction of selection indices across traits
- Pyramiding multiple genes for single/multiple traits
- Delivering improved germplasm and new cultivars
KIAAR is in the process of initiating new breeding program for abiotic stress resistance using marker assisted breeding.
