Abstract
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.
