ABSTRACT

The aim of the present study is to assess 100 sesame genotypes based on DUS descriptors. The experiment was conducted in Alpha Lattice Design with two replications at Regional Agricultural Research Station, Tirupati during rabi 2024-25. Based on the results of frequency distribution, a majority of sesame accessions were found to possess medium duration of 50% flowering with light purple petal colour, dense petal hairiness, medium plant branching, medium plant height, basal branching pattern, absent stem hairiness, medium leaf size, slightly lobed leaf, strong leaf serration, absent capsule hairiness, four locules per leaf axil, narrow oblong capsule shape, one capsule per leaf axil, alternate capsule arrangement, medium maturity, medium thousand seed weight, white seed coat colour and low oil content percent. The study highlights distinct morphological variations among sesame genotypes due to genetic differences, offering valuable insights for breeders in varietal selection, identification, and conservation.
