Paudel Hyacinth bean, diversity, traits, seed, high yield 89-95 7(4) 2023 October 2023 Hyacinth bean is an underutilized crop of great economic importance which belongs to Leguminosae family used for vegetable as well as pulse in Nepal. Ten genotypes were collected and evaluated for different qualitative and quantitative physico-morphological characteristics during 2022 at Central Terai of Nepal. The genotype showed some resemblance and variation among them for most of the morpho-physical character. The objectives of study were to find genotype with superior agronomic traits so that would further select in cultivation practice. Cotyledon, leaf color, leaflet length, leaflet width, vein color, stem color, petiole color, pod curvature, seed color, seed length and some other traits were observed which were varied among different genotype. Cotyledon color in unripe condition varied from light green, green to white. All of them were glabrous leaf surface and indeterminate in growth habit. The pod length varies from 3.5 cm to 12 cm and pod width varies from 1.1cm to 3cm. The genotype CNRMB-HB-1009 has highest flower bud size, pod length, seed per pod, seed length so was superior among them whereas CNRMB-HB-1008 has lowest pod length, pod width, seed length. The diversity of these crops can be used for hybridization and crop improvement in future days. Among these genotypes, simple selection might be used to create high-yielding cultivars
