| 總結: | Water buffaloes in Asia have been traditionally classified
into the swamp and the river types . Crossbreeding of these two
types has been practised in many Southeast Asian countries to reap
the advantages of heterosis and to optimize average genetic merit
and adaptability to t he harsh tropical environment .
Since both types of water buffalo have different chromosome
numbers ( swamp = 48 , river = 50) a study was undertaken to
determine the segregation pat terns of mitotic chromosomes through
various directions of cross breeding . The weight gain was also
estimated in the crossbreds so as to select the best crossbred carrying a particular proportion of swamp and river blood for
future breed improvement . This study also provides some information
on the reproductive status of the Flin relation to gamete and
embryo selection. |
