The State of the AJ &K- Pakistan is situated at the border of floristic
regions of the world, various vicarant taxa have been differentiated and
may hybridize in the same area and Pyrus is a good example. Biodiversity
in indigenous Pyrus germplasm accumulated through extreme diversity in
climate, geography, naturalized population and interspecific cross
pollination. Further, due to silk trade route system could be promoted
the phenomena of biodiversity in Pyrus species. Besides displaying high
resistance to biotic and abiotic stresses, diverse germplasm are
important for genetic improvement of pears. High diversity in pear
species is being eroded due to the ecological damage caused by global
warming and urbanization. Therefore, there is an urgent need to
investigate potential and limits of molecular technique, evaluate the
current genetic structure and classifying highly valuable genotypes.
Genetic markers representing highest genetic diversity to all genotypes
based on SSRs and Protein (SDS-PAGE) analysis showed the diversity in
protein profile need to be exploited. Present study would be helpful to
initiate breeding programme and to improve existing pear diverse
germplasm.
