| Abstract | Amorphophallus paeoniifolius (Dennst.) Nicolson is a tuberous herb occurring in the wild and cultivated state. Vegetative morphological characters were studied at full foliage stage in 17 accessions of A. paeoniifolius which include two cultivars, 15 wild accessions and a related species, A. dubius Blume. The first principal component (PC) accounted for 42.32% of phenotypic variance followed by second for another 18.38%. Major traits that accounted for more variability in both PC1 and PC2 include offset shape, cormel weight per corm, corm fresh weight, petiole surface pattern and canopy spread. The unweighted pair- group method with mathematical averaging (UPGMA) clustering method revealed three principal clusters which separated all the accessions between Euclidean distances of 0.3–1.6. Both cluster analysis and principal co-ordinate analysis revealed T10, a morphotype of A. paeoniifolius var. campanulatus (Decne.) Sivad. cultivated in Tamil Nadu and P19 accession of A. paeoniifolius var. paeoniifolius from Karnataka as morphologically distinct, which needs further validation on the basis of floral characters or molecular markers and G3 from Gujarat as an immediate ancestor of cultivated elephant foot yam. The genotypic (GCV) and phenotypic (PCV) coefficients of variation, broad sense heritability (h2B) and genetic advance (GA) as a percent of the mean assessed for 18 accessions revealed high heritability estimates. A highly significant (P < 0.01) correlation coefficient between circumference of petiole base and corm diameter, corm height, corm weight, east west spread and north south spread suggests that circumference of petiole and canopy spread are indicators to corm weight and size. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
