Abstract

The study was conducted at Dry Land Agriculture Research Station (DARS), Rangreth, Srinagar, Jammu and Kashmir, India aimed to comprehensively assess 40 genotypes, alongside 5 checks, for Distinctness, Uniformity and Stability (DUS) characterization. Employing an Augmented Block Design in the field in kharif season of April-August, 2022 and a Completely Randomized Design (CRD) in the laboratory from September–March 2023, the genotypes underwent evaluation for 21 DUS traits and 43 morphological, maturity, yield and quality traits. The evaluation followed descriptors specific to rajmash genotypes, utilizing frequency distribution based on “state” and “code” for each trait. The results indicated that majority of genotypes exhibited early flowering (<50 days), with 91% displaying an absence of anthocyanin coloration. Erect plant types were prevalent (51.11%), with 51% and 60% being viny and determinate, respectively. Most genotypes featured medium-sized, light green, ovate leaves (46.66%, 53%, and 22%, respectively). White-colored flowers (48.88%) with striped petal surfaces (57.77%) and medium curvature (40.00%) were predominant. Seed-related traits, such as cordate pod shapes (51%) and concave pod sutures (50%), along with acute pod distal shapes (69%), were observed. Pale green pods (57.77%) and 76% of genotypes exhibiting pod stringiness were noted. Seed shapes were mainly kidney-shaped (60%), and absent pigmentation in pod shells (73%) was observed. Large-sized seeds (40%) with dark red testa color (44%) were common, and seed testa variegation was “absent” in 75.55% of genotypes.
