Abstract
A field study was conducted to observe the DUS characters of 20 green gram (Vigna radiata L. Wilzeck) genotypes, during rabi season of 2019 at Varagoorpettai village and in Sivapuri Village during 2020, near Annamalai University (T.N), India. The present study was laid out in Randomized Block Design with three replications. The anthocyanin colouration was present in all 20 genotypes. Based on time of flowering, the genotypes were grouped as early (15 genotypes) and medium (5 genotype). Time of flowering varied with the genotype 30.15 days with (Chidambaram Local-1) to 44.33 days (DGGV 7) with an average of 37.84 days. Flower colour of petal was yellow in Maruvathur Local-1 while it was light yellow in 19 genotypes. Based on plant growth habit, the genotypes were grouped as erect (6 genotypes), semi erect (6 genotypes) and spreading (8 genotypes). Based on the plant habit, genotypes were grouped as indeterminate (16 genotypes) and determinate with (4 genotypes). Based on petiole colour, the genotypes were grouped as green (4 genotypes) and green with purple with (16 genotypes).Based on plant height, was long in DGGV 2 (73.57 cm), TAP 7 (73.47 cm), MH 421 (73.47 cm), CO 1(73.43 cm), Maruvathur Local-1 (72.33 cm) and Pusa Vishal (70.43 cm) and the lowest plant height was observed in ADT 3(51.47 cm).Based on stem morphology, stem colour was green (13 genotypes), whereas it was observed green with purple in (7 genotypes). All the 20 green gram genotypes evaluated did not show any variation for stem pubescence. Based on leaf morphology, the genotype Pusa Vishal was distinct genotype. On the basis of pod morphological characteristics, genotypes Maruvathur Local-1, KM 2, DGGV 2 were distinct. Seed colour was brown and seed lusture was shiny in 20 genotypes. For seed shape it was drum shape in (9 genotypes) and oval shape seeds in 11 genotypes.
