RÉSUMÉ
Leguminous crops are important components of Indian horticulture, because of being an important source of nutrition in predominantly vegetarian diet. In order to investigate the genetic diversity present in the underutilized legume sword bean genotypes of North-Eastern hill region of India 20 native sword bean (Canavalia gladiata Jacq.) genotypes were collected from different agroclimatic region of North-Eastern hill region of India. The morphological characters were observed in days to seed germination i.e. (3-6 days), pod length (16.45-32.87 cm), pod width (2.28-4.33 cm), pod weight (17.92-31.93 g), pod girth (7.75-12.64 mm) and seed weight (0.75-2.35 g). Performance of CHF SB-1, CHF SB-18, CHF SB-11, CHF SB-19, CHF SB-15, CHF SB-4 and CHF SB-10 genotypes under test conditions was superior and suggested that breeders might exploit the genome of these genotypes in current pulse crop improvement programmes.
RÉSUMÉ
The present study was conducted during the kharif season 2022 at the Vegetable Research Farm, located within the College of Horticulture and Forestry at Central Agricultural University in Pasighat, East Siang, Arunachal Pradesh, India to investigate “Evaluation of Morphological Traits in Cowpea [Vigna unguiculata (L.) Walp.] Genotypes Cultivated in North-East India”. These morphological traits demonstrated significant variation among the twenty locally accessible genotypes. Qualitative traits such as growth habit, twining habit, foliage colour, leaflet shape, flower colour, pod shape, pod colour, seed shape, seed colour were recorded. Quantitative characters such as days to 50% flowering, plant height (cm), leaf area (cm²), number of clusters per plant, number of pods per cluster, number of pods per plant, pod length (cm), pod width (cm), days to harvest, number of seeds per pod, 100 seed weight (g) and pod yield per plant (g) were studied. The mean performance revealed that CHF CP-12 gave highest pod yield per plant (589.19 g), highest 100 seed weight in CHF CP-12 (24.67 g), longest pod length in CHF CP-5 (32.77 cm), longest pod width in CHF CP-10 (1.07 cm), maximum number of clusters per plant was recorded in CHF CP-12 (14.16), maximum number of pods per plant in CHF CP-17 (11.80) and maximum leaf area was recorded in CHF CP-6 (229.30 cm²). The minimum number days taken for 50% flowering was found in genotypes CHF CP-9 (45.67).
