The investigation was undertaken at the Sagdividi Farm, Department of Seed Science and Technology, College of Agriculture, Junagadh Agricultural University, Junagadh, during kharif 2021 to DUS characterize 23 okra genotypes released for general cultivation in Gujarat at state level as well as at the National level in central India based on the qualitative characters. Observations for twenty three okra genotypes were recorded for 14 morphological and 2 seed characters. Okra genotypes were divided into two groups based on the colour of the stem: green (19 genotypes) and red (4 genotypes), while based on the intensity of the stem’s green colour, okra genotypes were grouped as light (20 genotypes) and medium (3 genotypes). All okra genotypes were divided into two groups based on the colour of the flower petals: cream (8 genotypes) and yellow (15 genotypes), while genotypes were divided into two groups based on the flower’s purple base petal colour: both side (18 genotypes) and inside (5 genotypes), while based on the fruit colour, okra genotypes were grouped as green (9 genotypes) and light green (11 genotypes). Based on the fruit surface between ridges, the 23 genotypes of okra were categorized as flat (20 genotypes) and convex (3 genotypes). The okra genotypes were categorized as absent (12 genotypes) and weak (11 genotypes) based on the constriction of the basal region of fruits. The okra genotypes were divided into three groups based on fruit pubescence: weak (16 genotypes), medium (2 genotypes) and strong (5 genotypes),
while okra genotypes were divided into three groups based on the shape of fruit apex: acute (15 genotypes), narrow acute (3 genotypes) and blunt (5 genotypes). All the 23 okra genotypes were having green colour between veins. The okra genotypes were divided into two groups: dark (18 genotypes) and medium (5 genotypes) based on the intensity of colour between veins. The okra genotypes were divided into light green (20 genotypes) and purple (3 genotypes) groups based on the colour of the leaf veins. Based on the depth of lobing, the genotypes were grouped as shallow (10 genotypes) and medium (13 genotypes), while based on the serration of leaf blade margin, the genotypes were grouped as weak (2 genotypes), medium (20 genotypes) and strong (1 genotype).
Based on the seed colour, the genotypes were grouped as brown (6 genotypes) and green (17 genotypes), while based on the seed hairiness, the genotypes were grouped as present (19 genotypes) and absent (4 genotypes).
