STUDIES ON KARYOTYPE OF SWAMP TYPE BUFFALOES OF ASSAM

摘要

The indigenous buffaloes of Assam are basically of Swamp type. Most of the workers reported the diploid chromosome number of Swamp buffaloes as 48 and Riverine buffaloes as 50. The crossbreeds of Riverine and Swamp buffaloes are reported to have exhibited reproductive disturbances which are more pronounced in males (Basrur, 1986), females are less affected in their fertility (Basrur, et al., 1988). Reports on the diploid chromosome number of Swamp type buffaloes of Assam is very scanty. Therefore, the preset study was undertaken for karyotyping of indigenous buffaloes of Assam which will help in formulating breeding policy to improve the production performances of these buffaloes through introduction of outstanding riverine buffaloes.
