Heterotic hybrid


Heterotic hybrid

    Development of heterotic hybrid:
    • Molecular markers based analysis can be utilized to identify specific genomic regions containing QTLS for yield showing dominance or over-dominance gene action in f2 of a cross between two inbred lines.
    • This will enable analysis of an existing cross in terms of the number of QTLS involved and the magnitude of there effect on the measured trait. Subsequently additional Inbredlines can be tested against standard lines for the presence of additional dominant or over-dominant QTLS. These could then be incorporated into the standard lines by marker based introgression. In this way existing inbred can be improved first and then used to develop hybrids for realizing higher heterosis than in the existing ones.
