Quality of tea is invariably associated with the region where it is grown. Higher the altitude of the growing region, better should be the drinking quality of the tea. It is true that the genetic profiles of different varieties of plants within a species have a profound influence on the quality of the end product but a particular variety with a specific genetic profile need not give same quality products if grown under different conditions. This has been brought out in the case of tea by researchers recently.
"The results showed significant differences in the quality of the plain tea produced among the varying locations of production. A closer look further indicated that the changes in the tea were not systematic, because the same genotype reflected different changes in different regions. The study led the team to conclude: "A genotype selected in one site for high quality may not retain the relative quality over other genotypes in new areas. It is necessary to test genotypes in new areas of production to fully evaluate their relative quality potentials."
Probably such an endowment can be a restraint for smuggling seed materials across the borders since there is no guarantee that these seeds will produce same quality products when grown out side the country from where they have been taken out. of course the advent of IP rights regime for Geographical Indications, many unique plant materials have got recognition, making trans-border transplantation a bit more difficult.
