According to UPOV Convention 1961, Distinctiveness, Uniformity and Stability (DUS) testing is essential to provide

and promote an effective system of plant variety protection, with the aim of encouraging the development of new

varieties of plants and for the benefit of society. It provides rights for eeders and farmers to exploit or develop new plant varieties, to allow

access to foreign varieties with widen gene pool, to promote intensive eeding activities and to prevent unauthorized varieties exploitations.

In the present study, 50 hyids of Phalaenopsiswere evaluated for development of DUS test guidelines using common descriptors. Out of 58

common descriptors developed, plant size, flower width in front view, petal predominant colour and colour pattern, predominant colour and

colour pattern of apical lobe of lip were used for grouping of hyids.
