The rebels, who are Independent MLAs, had served as ministers in the BJP government, sources said.
In a meeting of the Central Election Committee chaired by party President Sonia Gandhi, the party held threadbare discussions on the names of candidates suggested by the AICC's Screening Committee.
The Independents given tickets are Narendra Swamy, Venkataramanappa, Sudhakar and Shivaraj Thangadi. The lone Congress rebel and Independent MLA who does not figure in the list is Goolihatti Shekhar, the sources said.
A number of Congress MLAs had resigned from their seats, which they later contested as BJP candidates in by-polls and won under Operation Lotus, when B S Yeddyurappa was chief minister.
Buoyed by its recent success in civic polls in the state and the exit of Yeddyurappa from the BJP, Congress leaders are confident of wresting power from the Opposition party in Karnataka, which was the maiden "lotus bloom" for the BJP in southern India.
As part of its poll exercises, the party has already set up a high-level coordination and monitoring committee headed by Defence Minister A K Antony with senior Union ministers as its members, first of its kind for any particular state assembly election.
