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...

Pear belongs to genus Pyrus, abundantly found in temperate region of AJ & K reflects rich biodiversity. Such diversity and valuable genetic resources are being eroded due to human over exploitation, and natural calamities. Keeping in view existing genetic diversity and genetic erosion in Pyrus germplasm, the focus of present study was to develop biotechnological conservation strategies by using slow-growth techniques. However in vivo preservation was also implemented to conserve the basic stock under field conditions. The apical shoots of nine pear genotypes were preserved in vitro under...

Mango (Mangifera indica L.) is known as "king of fruits" due to its delicious taste and unique flavor. It is an important tropical fruit, belongs to family Anacardiaceae, and has been cultivated all over the world. Mango is major fruit owing to its particular climatic requirements, taste, high nutritive value, its demand and trade is rapidly expanding across the globe. Mango orchards suffering different kind of problems in nursery, poor health of tree (field), quick decline, infestation of insects and pests and lack of proper nutrition, which are principles reasons for devastation of mango...
