The theory of back-crossing: Back-crossing is crossing of F.1 hybrid with either of its parents. That parent of the hybrid with which it is again crossed, or with which it is repeatedly crossed is the back-cross parent or recurrent parent the other parent being the donor parent or non-recurrent parent (Knight, 1948) The principle involved in the use of the back-cross technique is the simple one of reducing the amount of genetic variance in the material in which selection is to be practised (Hutchinson et al, 1938). Thus, relatively small population need only be raised to select out the desirable genotype, if back-crossing is resorted, to.
