- Abstract
Genetic diversity of 63 entries of Arracacha was studied by estimating 25 morphological and agronomical descriptors during 2007 and 2008. The selected entries were classified into twelve groups based on the identical and correlated morphological and agronomical traits. The selected traits were 19 main characters. Five characteristics were excluded as they did not show much variability. Morphological characteristics did not show much variation. Some characteristics like root yield, number of roots and number of shoots showed more. A sampling intensity of 30% was found to represent the core collection since it showed 87.09% determination coefficient (R²) and 96.67% coincidence rate (CR). Entries BHG-4551 and BHG- 7628 were duplicated.
