The studies were undertaken to develop DUS testing guidelines of 10 varieties of watermelon [Citrullus lanatus (Thunb) Matsam & Nakai] during 2011–2013 at CIAH, Bikaner. The results revealed that all varieties showed considerable variation in qualitative and quantitative characters. All varieties were grouped into different categories for each character based on 27 descriptors which may be used as reference varieties. The traits like degree of primary lobing of leaf blade, fruit shape in longitudinal section, rind colour of fruit, fruit stripes, fruit size, flesh colour, seediness of fruits and colour of seed coat were identified as grouping traits. The characterization of extant varieties was completed to establish distinctness of candidate variety from all other varieties to utilize these varieties as reference material for protection of other varieties under PPV&FR Act, 2001.
