Induce breeding to develop backcross generations of Catla catla (Ham.) and Labeo rohita (Ham.)


Subodh Kumar Tripathy, Niranjan Sarangi

The study was undertaken to develop different backcross generations of Catla catla (Ham.) and Labeo rohita (Ham.) i.e. B1 (CRxC), B2 (CRxR), B1R (CRxC)x R and BC1F2 (CRxC)x(CRxC) in Central Agricultural Research Institute (CARI), Port Blair, South Andaman, India, by induce breeding through hypophysation. Three different hormones viz- Pituitary Gland Extract (PGE), Ovaprim and Ovatide were employed as per recommendation. Full release of eggs followed by good hatching in different experimental sets depicted 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
