摘要：The present investigation was undertaken with the objective of DUS characterisation of advanced recombinant lines of Kalanamak rice for 47 visually assessed characters and 15 quantitative characters. Trials were conducted for two seasons during Kharif 2016 and 2017 at Norman E. Borlaug Crop Research Centre (NEBCRC), G. B. Pant University of Agriculture and Technology (GBPUAT), Pantnagar, Uttarakhand in a Randomized Complete Block Design (RCBD) in three replications with the spacing of 20 cm × 15 cm and the recommended cultural practices were followed. For this data were recorded for sixty-two DUS descriptors following the guidelines of the International Union for the Protection of New Varieties of Plants (UPOV) and the Protection of Plant Varieties and Farmer’s Rights Authority (PPVandFRA). In the present study, 27 visually assessed characteristics are found to be monomorphic, 18 are dimorphic and 2 are polymorphic. KARL10 with higher yield, intermediate amylose content, early 50% flowering and early maturity is reported to be best genotypes in respect of desired characteristics and could be used as a potential source for deriving improved lines through selection.
