Study of Genetic Relatedness among Meat Producing Indian Sheep Breeds by RAPD-PCR

Abstract

Hatkar, D.N., Prince, L.L.L., Sirothia, A.R. and Paswan, C. 2008. Study of genetic relatedness among meat producing Indian sheep breeds by RAPD-PCR. J. Appl. Anim. Res., 38: 129–133.

To estimate the genetic variability and phylogenetic relationship among four breeds (Sonadi, Madgyal, Deccani and Nellore) of sheep adapted in the semi-arid climatic conditions of Rajasthan and part of Deccan plateau RAPD technique was applied. This analysis kept the four breeds in three groups i.e. Deccani and Nellore were kept in same group, Sonadi and Madgyal were kept in entirely different groups but Madgyal has more closenese to Deccani and Nellore. This RAPD marker study revealed that Madgyal, Deccani and Nellore are closer genetically as compared to Sonadi breed.

Keywords:

• Indian sheep breeds
