AB  - The present study was undertaken to develop different
backcross generations of Catla catla (Ham.) and Labeo rohita
(Ham.), i.e., B<sub>1</sub> (CRxC), B<sub>2</sub> (CRxR), B<sub>1</sub>R (CRxC)x R and BC<sub>1</sub>F<sub>2</sub>
(CRxC)x(CRxC) in Central Agricultural Research Institute
(CARI), Port Blair, South Andaman, India, using the technique of
induce breeding through hypophysation. Three different inducing
hormones viz-Pituitary Gland Extract (PGE), Ovaprim and Ovatide
were employed as per their recommended dose. Full release of
eggs followed by good hatching in different experimental sets
depicts the success of breeding. It is the first application of the
concept of backcross breeding in IMC like rohu and catla. All the
hybrids and backcross generations developed were highly viable
and fertile. The success of breeding the backcrosses may be
attributed to nature itself which accepted inter-generic
hybridization resulting in viable hybrids. The success of
developing the backcross generations is significant for carp
genetics with special reference to catla and rohu.
