German Chancellor Angela Merkel's Bavarian allies have scored a resounding state election win, exit polls show.
The result gives her a strong boost a week ahead of a general election.
The conservative ruling Christian Social Union, the Bavarian sister party of Merkel's Christian Democrats, captured an absolute majority of seats in the regional parliament with 49 per cent of the vote, according to Sunday exit polls on public television.
Its outsized victory means it can drop its junior partners, the pro-business Free Democrats (FDP), who crashed out of the regional parliament with a disastrous three per cent.
Merkel campaigned heavily in the state's world-famous beer tents, pointing out that a big win in Bavaria would lend momentum to her bid for a third term at the helm of Europe's top economic power.

National polls give Merkel's conservatives an around 14-point lead over the main opposition Social Democrats (SPD), who scored about 21 per cent in Bavaria, historically a conservative state.
The ecologist Greens turned in a dismal 8.5 per cent, in keeping with a downward trend on the national level.
The CSU has ruled Bavaria uninterrupted for 56 years with a winning strategy of "laptops and lederhosen" - high-tech business savvy coupled with proud tradition.
Led by outspoken state premier Horst Seehofer, the CSU saw big gains from its 43 per cent score at the last election in 2008, when it lost its absolute majority.
Some 9.5 million were eligible to vote in the wealthy, predominantly Catholic southern region that is home to German industrial giants such as BMW, Audi and Siemens.
