ABSTRACTDirect planting (i.e. the planting of seed roots) can reduce the labor requirements of sweet potato (Ipomoea batatas (L.) Lam.) cultivation. To broaden the breeding material for high dry matter productivity in direct planting, root dry matter content (DMC) and root dry matter weight per hill (DMW) were compared under both direct planting and conventional transplanting by using 28 sweet potato genotypes cultivated in 2020 and 2021. Unlike in the case of the mother root DMC, a significant positive correlation between the daughter root DMC in direct planting and the root DMC in transplanting was observed over two years (p
