‘- ‘and ‘+’ signs indicate negative and positive correlation between the traits studied in this experiment, respectively. *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001, ^ns: Non significant.

VL = vine length, ARL = average storage root length, ARD = average storage root diameter, MRN = marketable storage root number per plant, MRY = marketable storage root yield, ARN = average storage root number per plant, ARW = average storage root weight per plant, NMRY = non-marketable storage root yield, DW = dry weight of storage root.
