Popis: Direct planting (i.e. the planting of seed roots) in sweet potato results in the formation of two root types – ‘mother’ and ‘daughter’ roots. High and stable daughter root yields are necessary to improve the acceptance of direct planting cultivation because mother roots have no commercial value. To establish a basis for the effective breeding, the root traits of 28 sweet potato genotypes cultivated by direct planting were evaluated for mother root weight, daughter root weight (DRW), total root weight (TRW), ratio of DRW to TRW (RDRW), and ratio of mother root enlargement. Significant differences between the genotypes were observed for all five traits (p
