An example germplasm characterisation data of a core collection generated
from 1591 accessions of IITA Cassava collection
(International Institute of Tropical Agriculture et al. 2019)
using 10 quantitative and 48 qualitative trait data with CoreHunter3
(corehunter). The core set was generated using
distance based measures giving equal weightage to Average
entry-to-nearest-entry distance (EN) and Average accession-to-nearest-entry
distance (AN). Includes data on 26 descriptors for 168 (10 % of
cassava_EC) accessions. It is used to demonstrate
the various functions of EvaluateCore package.
