"There is a danger that charlatans and neo-Nazis could seize this disgraceful work when Bavaria's rights run out. Therefore I am of the opinion there should be a decently prepared and well-grounded critical edition," the statement cited Heubisch as telling an event on Friday.
"Mein Kampf" ("My Struggle") has been banned in Germany since the end of World War II, and the state of Bavaria holds the rights until 70 years after the Nazi dictator's death in 1945.
Jewish groups and historians have long spoken out for an annotated edition.
In January British publisher Peter McGee caused a stir when he began selling reprints in Germany of the Nazi newspaper Voelkischer Beobachter (People's Observer) with comments from historians.
Bavaria launched a legal challenge to the series, known as "Zeitungszeugen" ("Newspaper Witnesses"), but succeeded only in blocking the sale of editions from after the outbreak of war in 1939.
