Abstract
Characterisation and evaluation of native germplasm are fundamental for facilitating genetic improvement, safeguarding varieties,
and conserving biodiversity. In this study, thirty-two dahlia (Dahlia variabilis L.) genotypes were evaluated over two consecutive years
(2022–23) and (2023–24) at the Regional Horticultural Research and Training Station (RHRTS) Dhaulakuan, Sirmour (H.P).
Morphological characteristics (51) were used for the identification and grouping of dahlia genotypes. A set of 51 morphological traits
was used to distinguish and classify the genotypes in line with the DUS (Distinctiveness, Uniformity, Stability) testing framework
developed by RHRTS, Dhaulakuan, Sirmour, in collaboration with BCKV, Kalyani (West Bengal) funded by PPV & FRA, India. The DUS
characteristic profile was developed for all 32 genotypes, enabling clear varietal grouping and identification.
