PROBLEM TO BE SOLVED: To improve work efficiency of a grafting work, improve junction accuracy of grafted seedlings, and obtain excellent grafted seedlings.SOLUTION: In a grafted seedling producing apparatus, a rootstock intake section is provided on one of right/left sides of a grafting robot main body la, a scion intake section is provided on the other of right/left sides of the grafting robot main body la. The rootstock intake section and the scion intake section include: a carry-in mechanism 11 which carries in a seedling tray that houses seedlings a gripping hand 12 which grips and takes out a seedling from the seedling tray on the carry-in mechanism 11 and supplies it to the grafting robot main body la side and a position change mechanism which changes positional relationship between the carry-in mechanism 11 and the gripping hand 12. The apparatus is provided with an operation device 157 which operates the position change mechanism of the rootstock intake section and the scion intake section, a holding body 159 which holds the operation device 157 is provided so as to be displaced to the rootstock intake section side or the scion intake section side from the lateral central position of the grafting robot main body 1a, and the operation device 157 is removed from the holding body 159 to be movably configured.
