Online Published on 20 December, 2022. Abstract The distinctness of a candidate variety from previously released varieties is a major criterion for granting of plant breeders’ rights. At the same time, there is a need to maintain the genetic purity of varieties during seed production and certification programmes. Twenty nine lentil recombinant inbred lines (RILs) were assessed at two locations along with two checks viz Markanday and Vipasha for their distinctness, uniformity and stability (DUS) under Protection of Plant Varieties and Farmer’s Rights (PPV & FR) Act 2001. All these genotypes were categorized based on three quantitative and ten qualitative descriptors. The variability in the expression of these distinguishing traits was observed at seed and plant levels. Seed size, seed colour, foliage colour, anthocyanin colouration on stem, leaflet size, plant growth habit and plant height were found to be the most useful characters for sound classification of genotypes and utilization in strengthening of lentil breeding programmes.
