The objectives of this study were (i) determining genetic diversity among C. arietinum and C. reticulatum species (ii) identification of marker-trait associations for Cu, P and K nutrients in seeds of chickpea (iii) identification of the impact of environment and genotype (iv) identification of candidate genes with related to the markers associated with Cu, P and K nutrient uptake by annotation in BLAST.
This is the first study revealing the marker-trait associations and environmental interactions for Cu, P and K concentrations in Cicer seeds with a large population of both C. arietinum and C. reticulatum species with many environmental parameters. Identified markers, candidate genes and suggested methods such as GBS technology provides broader understanding for future research and can also be used in marker-assisted selection for biofortification of chickpea seeds in breeding programmes.
This research suggested that association mapping and use of GBS technology are powerful methodologies for identification of marker-trait associations and the effects of environmental conditions for Cu, P and K uptake in chickpea seeds for and provides broader understanding for further association mapping, molecular breeding, and marker-assisted selection studies.Esin Ozkuru
