Thank you very much Farook Sahib
Yes I did read the article and I found it tremendously interesting, I did further research on the desi rose breeder Rudolf Gerchwind and found a nursery (
http://www.rosen-weingart.de/ )in Germany that supplies several of the original breeders hybrid roses including our desi rose and a more rare one named Fernand Krier, a sport of Excelsa with flowers of three different colours on the same plant name red and white and blotched red/white.

I am probably now sounding too much indepth but Gruss an Teplitz ( desi rose ) has only been bred and introduced since 1897 then our gulkand and rosewater recipe utilising rosepetals predates that period.
The original question still remains. Which is the rose that has been used for making the delicacy Gulkand.
My suspicion according to the following article is that it Rosa x Damascena. Apparently the rose has been used since biblical times in the middle east (later in india and Bulgaria) to produce rose water. Presumably this would have occurred with the ancient spice route trails from China, Russia, Northern India/Pakistan, Central Asia, Middle East and then onto Europe, as there is also significant history of rose water production in Afghanistan

Please excuse me for sounding pedantic but I find the historical perspectives fascinating and just wish to find the different older varieties that can be used for making Gulkand.
My favourite at the moment is Rosa x Damascene, mother must have used the next best substitute by smell, flavour and texture as the correct one was not cultivated in the area. It was during the 1960s in a Lancashire mill town. Predominantly densely packed terraced houses a few of which had the luxury of tiny front gardens.
