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.
