Genomic Basis of Defining Heterotic Pools in Pigeonpea (Cajanus cajan L.): A Review

Hybrid breeding strategy leading to define heterotic pools expedited execution of hybrid technology for amelioration of yield, quality, wide adaptability and resistance to biotic and abiotic stresses. In case of pigeonpea conventional hybrid breeding programme has yielded good dividends, yet it can be further honed up by understanding the genome wide variations in the hybrid parental lines for defining heterotic pools. Also, combining ability basis of defining heterotic pools offer enormous opportunities for pragmatic exploitation of pigeonpea hybrid technology with high yield advantages realized in farmers’ fields.
